Low-current protection circuits require a different approach from conventional power distribution. When the protected load operates at only a small fraction of the current handled by typical distribution breakers, the protection device must be selected with particular attention to its rated current, tripping behaviour, pole arrangement, and fault interruption capability.

The Schneider Electric A9F93301 is an Acti9 iC60L miniature circuit breaker designed with three protected poles, a 1 A rated current, and a B-curve thermal-magnetic trip unit. This configuration provides coordinated protection for suitable three-phase circuits where the operating current is relatively low and a B-type tripping characteristic is required.

The 1 A rating makes this model appropriate for circuits where the permissible current is limited. Instead of serving as a high-load feeder protection device, it is intended for electrical systems in which accurate matching between the protective device and the connected circuit is essential.

The B-curve characteristic determines how the breaker responds when the current rises sharply. Its magnetic tripping threshold is set at approximately 4 times the rated current, with a tolerance of ±20%, giving the device a comparatively sensitive instantaneous response. This characteristic is generally appropriate for circuits where substantial starting or inrush currents are not expected.

Another important characteristic is the breaker’s short-circuit performance. The A9F93301 provides a 15 kA rated short-circuit breaking capacity at 400 V AC according to EN/IEC 60898-1. Under EN/IEC 60947-2, the ultimate breaking capacity reaches 100 kA at 380–415 V AC. The specified interruption ratings vary with the operating voltage and include a 70 kA Icu at 440 V AC. For DC applications, the specified Icu reaches 20 kA at voltages up to 180 V DC.

The three-pole configuration protects all three poles and provides simultaneous circuit protection within a single modular device. This arrangement is particularly useful in electrical panels where three-phase circuit protection needs to remain compact and clearly organised.

The Acti9 iC60L platform also incorporates functions intended for professional electrical installations. The A9F93301 supports electrical isolation according to the applicable standards and can be combined with compatible auxiliary devices, remote monitoring equipment, and Vigi residual-current protection. Schneider Electric also identifies Visitrip and VisiSafe functions within the product platform for improved fault identification and safer circuit protection.

Schneider Electric A9F93301 Technical Specifications

The A9F93301 has a clearly defined protection profile based on its 1 A rated current, three protected poles, and B-curve characteristic. These parameters work together to determine where the breaker can be installed and how it will react to abnormal operating conditions.

Its interruption capability is notably high in relation to its nominal current. A breaker rated at only 1 A can therefore still be appropriate for an installation with a considerable prospective short-circuit current, provided that the voltage, fault level, and other installation parameters remain within the specified limits.

Rated Current – 1 A

The 1 A rated current defines the nominal operating current of the A9F93301. This rating is suited to circuits where the load and conductors require relatively low-current protection.

Selecting a 1 A breaker requires more than simply comparing the nominal load current with the breaker rating. Conductor capacity, ambient temperature, installation method, upstream protection, and the operating characteristics of the connected equipment all contribute to correct circuit protection.

B-Curve Tripping Characteristic

The A9F93301 uses a B-curve tripping characteristic with a magnetic tripping limit of approximately 4 × In ±20%. With a 1 A rated current, this establishes a comparatively sensitive instantaneous response to substantial current increases.

The B curve is therefore better suited to circuits where significant inrush currents are not expected. Selecting it for loads with strong starting currents without checking the transient behaviour of the circuit can result in unwanted interruptions.

Three-Pole Protection

All three poles are protected in the A9F93301. The 3P configuration allows the device to protect a three-phase circuit through a single coordinated breaker.

This arrangement simplifies the protection architecture of the panel and provides a compact solution where simultaneous disconnection and protection of three conductors are required.

Short-Circuit Breaking Capacity

At 400 V AC, the A9F93301 provides a 15 kA Icn according to EN/IEC 60898-1. Under EN/IEC 60947-2, the breaker reaches 100 kA Icu at 380–415 V AC, 100 kA at 220–240 V AC, and 70 kA at 440 V AC. The specified DC interruption capability reaches 20 kA at ≤180 V DC.

These ratings indicate the maximum fault interruption capability under the conditions defined by the relevant standards. The prospective short-circuit current at the actual installation point should always be established before selecting the breaker.

Thermal-Magnetic Protection

The A9F93301 uses thermal-magnetic trip technology. Its thermal mechanism reacts to sustained overload conditions, while the magnetic mechanism provides rapid disconnection during high-current fault events.

This combination allows the same breaker to address both prolonged overcurrent and short-circuit conditions without requiring separate protection mechanisms.

AC and DC Operation

The A9F93301 is specified for AC and DC networks. For AC systems, the device operates across several rated voltage ranges from 12–133 V AC to 440 V AC, depending on the applicable configuration. The product data also specifies a 20 kA Icu at ≤180 V DC.

AC and DC interruption ratings should not be treated as interchangeable. The operating voltage and circuit arrangement determine which breaking-capacity value applies.

Features and Benefits of the Schneider Electric A9F93301

The A9F93301 is designed around a combination of low nominal current and relatively high fault interruption capability. Its 1 A rating makes it suitable for low-current circuits, while its 15 kA Icn at 400 V AC provides a substantial short-circuit interruption level for this class of device.

The B-curve characteristic gives the breaker a defined magnetic response for circuits where lower instantaneous tripping thresholds are required. The three protected poles also allow coordinated protection of a three-phase circuit without using separate single-pole devices.

Its Acti9 iC60L architecture provides additional installation flexibility through compatible accessories and monitoring solutions. The breaker can be incorporated into modular protection assemblies where auxiliary signalling, remote supervision, or residual-current protection is required.

Key Benefits

The Schneider Electric A9F93301 provides three-pole protection for low-current circuits while combining thermal overload protection with magnetic short-circuit protection. Its B-curve response is suitable for circuits with limited inrush current, and its high interruption ratings provide additional fault protection capability.

The device also supports electrical isolation, modular panel installation, and integration with compatible Acti9 accessories, making it suitable for professional electrical distribution and control assemblies.

Applications of the Schneider Electric A9F93301 Miniature Circuit Breaker

The A9F93301 is most appropriate where a 1 A rated current, 3P configuration, and B-curve response correspond to the electrical requirements of the protected circuit.

Three-Phase Control Circuits

Low-current three-phase control circuits can require individual protection when the connected equipment operates well below the current levels associated with conventional power feeders. The three protected poles of the A9F93301 provide coordinated protection within a single device.

Instrumentation Systems

Instrumentation circuits can contain sensitive components and relatively small conductors that require closely matched overcurrent protection. The 1 A rating and B-curve characteristic can be appropriate for such circuits when their operating characteristics are compatible with the breaker.

Industrial Auxiliary Circuits

Industrial installations often contain auxiliary circuits that support larger machines and distribution systems. Independent circuit protection can prevent faults within these smaller circuits from affecting unrelated parts of the installation.

Automation Panels

Automation cabinets commonly contain numerous low-current circuits for control, signalling, and auxiliary functions. The compact 3P configuration of the A9F93301 allows suitable three-phase circuits to be protected while maintaining an organised modular panel layout.

Electrical Distribution Assemblies

Selected low-current outgoing circuits within distribution assemblies can benefit from dedicated three-pole protection. The A9F93301 can provide this function where its current rating, B curve, voltage, and breaking capacity match the installation requirements.

Low-Power Industrial Equipment

Equipment with relatively low operating currents can require protection that is more precisely matched to its electrical characteristics than a general-purpose high-current breaker. The A9F93301 provides a 1 A protection option for applications meeting its technical requirements.

Why Buy the Schneider Electric A9F93301?

The Schneider Electric A9F93301 combines a 1 A rated current, 3P configuration, B-curve characteristic, and thermal-magnetic protection in the Acti9 iC60L platform. This combination provides a specific protection profile that should be matched to the electrical behaviour of the circuit rather than selected solely on the basis of physical dimensions or nominal voltage.

The model also provides a substantial short-circuit interruption capability relative to its current rating. This allows it to be considered for installations where the protected circuit carries only a small current but the available fault current at the installation point is considerably higher.

Advantages of Choosing the Right Model

Correct breaker selection establishes the relationship between the circuit load, conductor capacity, tripping characteristic, and prospective fault current. The A9F93301 provides a defined 1 A B-curve solution for applications requiring three protected poles and sensitive magnetic protection.
