Reliable protection is essential in electrical systems where even a minor fault can affect sensitive equipment, interrupt control functions, or create wider operational problems. Miniature circuit breakers are commonly used to isolate affected circuits when abnormal current conditions occur, helping protect conductors and connected equipment from the consequences of overloads and short circuits.

The Schneider Electric A9F92302 is an Acti9 iC60L miniature circuit breaker designed for low-voltage applications requiring a compact three-pole protection device. With a 2 A rated current, Z-curve tripping characteristic, and thermal-magnetic trip technology, it provides a sensitive protection response for circuits where precise overcurrent protection is required.

The three-pole configuration allows the A9F92302 to protect three circuits within a single modular device, making it suitable for selected three-phase control and auxiliary applications. Its 400 V AC rated voltage, 50/60 Hz operating frequency, and compatibility with both AC and DC systems provide additional flexibility when designing electrical panels and control assemblies.

Short-circuit performance is another important characteristic of this model. The A9F92302 provides a 15 kA breaking capacity at 400 V AC according to IEC/EN 60898-1. Under IEC/EN 60947-2, the ultimate breaking capacity reaches 100 kA at 380–415 V AC, while the device can achieve 70 kA at 440 V AC under the specified conditions. This high interruption capability allows the breaker to be considered for installations where prospective fault currents must be carefully evaluated.

The Z-curve characteristic gives the A9F92302 a more sensitive tripping profile than circuit breakers intended for circuits with higher temporary inrush currents. This makes accurate application and coordination particularly important, especially when the breaker is used with electronic equipment, control circuits, automation components, or other sensitive loads.

The compact design of the Acti9 iC60L range also simplifies integration into modular electrical assemblies. DIN-rail mounting allows the breaker to be installed alongside other protection, switching, and monitoring components, while compatible Acti9 accessories can extend the functionality of the installation.

Schneider Electric A9F92302 Technical Specifications

The electrical characteristics of a miniature circuit breaker determine how it behaves during both normal operation and fault conditions. For the A9F92302, the combination of a 2 A rated current, 3-pole configuration, Z-curve tripping, and thermal-magnetic protection defines its intended protection profile.

Breaking capacity must also be considered when evaluating this circuit breaker for an installation. The model provides 15 kA Icn at 400 V AC under IEC/EN 60898-1 and up to 100 kA Icu at 380–415 V AC under IEC/EN 60947-2. These ratings should be compared with the prospective short-circuit current of the installation before the breaker is selected.

Rated Current – 2 A

The 2 A rated current identifies the nominal current level associated with the A9F92302 under its specified operating conditions. This relatively low current rating makes the model relevant to control, auxiliary, automation, and other circuits where higher-rated protection would not provide the required level of circuit coordination.

The breaker rating should always be matched with the conductor capacity, connected load, and overall protection arrangement. Correct coordination helps prevent nuisance tripping during normal operation while maintaining effective protection when abnormal current conditions develop.

Z-Curve Tripping Characteristic

The A9F92302 uses a Z-curve tripping characteristic designed for sensitive circuit protection. Compared with characteristics intended to tolerate greater inrush currents, the Z curve responds at lower instantaneous overcurrent levels.

This characteristic can be useful in circuits containing sensitive electrical or electronic equipment, provided that the expected operating current and transient behavior of the connected load are compatible with the selected breaker.

Three-Pole Configuration

The 3P configuration provides protection across three poles within one compact circuit breaker. This arrangement is particularly useful in three-phase electrical systems where coordinated protection is required without installing separate single-pole devices.

Three protected poles also provide a practical solution for control panels and distribution assemblies where panel space and organized circuit protection are important design considerations.

Breaking Capacity – 15 kA

At 400 V AC and 50/60 Hz, the A9F92302 has a 15 kA Icn breaking capacity according to IEC/EN 60898-1. This represents the short-circuit current level that the device is designed to interrupt under the conditions defined by the applicable standard.

Under IEC/EN 60947-2, the model provides an Icu of up to 100 kA at 380–415 V AC and 70 kA at 440 V AC. The applicable breaking capacity must always be evaluated according to the actual operating voltage and installation conditions.

Thermal-Magnetic Protection

The A9F92302 uses a thermal-magnetic trip unit to address both sustained overloads and high fault currents. The thermal mechanism responds to prolonged overcurrent conditions, while the magnetic mechanism provides rapid operation when a significant short-circuit current occurs.

This combination gives the breaker two complementary protection mechanisms within a single compact device.

AC and DC Compatibility

The A9F92302 is designed for use in AC and DC networks, with the applicable interruption ratings depending on the voltage and circuit configuration. This capability makes the device suitable for a range of low-voltage protection applications where the electrical characteristics fall within its specified ratings.

Features and Benefits of the Schneider Electric A9F92302

The A9F92302 combines sensitive circuit protection with a compact three-pole construction. Its 2 A rated current, Z-curve characteristic, and thermal-magnetic trip technology provide a defined protection profile for low-current circuits.

Its high short-circuit interruption capability is another important advantage. With a 15 kA Icn at 400 V AC and an Icu of up to 100 kA at 380–415 V AC, the breaker can be considered for installations where the available fault current requires a protection device with substantial interruption capability.

DIN-rail mounting makes installation straightforward in modular electrical panels, while the Acti9 iC60L platform allows the breaker to be combined with compatible auxiliary, monitoring, and residual-current protection devices.

Key Benefits

The Schneider Electric A9F92302 provides sensitive Z-curve protection for low-current circuits while maintaining three-pole circuit protection in a compact modular format. Its thermal-magnetic protection technology addresses both overload and short-circuit conditions, while its high breaking capacity provides additional protection capability in installations with significant prospective fault currents.

The device also offers AC/DC compatibility, DIN-rail mounting, and integration with the wider Acti9 accessory ecosystem, giving panel designers additional flexibility when configuring electrical protection systems.
