Electrical circuits that supply sensitive components often require protection that reacts more quickly to abnormal current conditions than conventional general-purpose breakers. Selecting the correct miniature circuit breaker therefore depends not only on the rated current, but also on the number of protected poles and the required instantaneous tripping behaviour.

The Schneider Electric A9F92401 belongs to the Acti9 iC60L family and is configured as a 4-pole miniature circuit breaker with a 1 A rated current and Z tripping characteristic. All four poles are protected, providing simultaneous circuit protection for applications where four-pole isolation and overcurrent protection are required.

The breaker incorporates thermal-magnetic protection, allowing it to respond to both prolonged overload conditions and high-current short-circuit events. It is designed for AC/DC networks, with a 400 V AC rated voltage and 50/60 Hz operating frequency for AC installations.

Fault interruption is one of the key characteristics of the iC60L platform. The A9F92401 offers a 15 kA rated breaking capacity at 400 V AC in accordance with IEC/EN 60898-1. Under IEC/EN 60947-2, its ultimate breaking capacity can reach 100 kA at 380–415 V AC, while a 100 kA Icu rating is also specified at 220–240 V AC under the applicable conditions.

The Z tripping curve gives this circuit breaker a particularly sensitive instantaneous response. Schneider Electric identifies the Z characteristic as appropriate for applications requiring sensitive protection, including certain semiconductor-related circuits.

The four-pole arrangement makes the A9F92401 different from comparable 1 A versions with fewer poles. It can protect four conductors simultaneously and can be incorporated into modular electrical assemblies using standard 35 mm DIN-rail mounting.

The Acti9 iC60L platform also allows compatible auxiliary and monitoring accessories to be added where the electrical installation requires additional signalling, remote monitoring, or residual-current protection functions.

A9F92401 Electrical and Mechanical Characteristics

The performance of a miniature circuit breaker is determined by the relationship between its rated current, tripping behaviour, pole configuration, voltage rating, and short-circuit capability. In the case of the A9F92401, these characteristics are combined into a 4P, 1 A, Z-curve protection device intended for specialised low-current applications.

Its short-circuit capability is particularly notable for a breaker in this current class. The device provides 15 kA Icn at both 230 V AC and 400 V AC according to EN/IEC 60898-1, while IEC/EN 60947-2 specifies 100 kA Icu at 220–240 V AC and 380–415 V AC under the applicable test conditions.

1 A Current Rating

With a 1 A nominal current, the A9F92401 is intended for circuits where the expected operating current is relatively low. This makes it relevant to specialised protection requirements rather than conventional high-load distribution circuits.

The rated current should always be selected in relation to the conductor ampacity, connected equipment, and expected operating conditions. A correctly selected rating helps prevent excessive current from remaining in the circuit while avoiding unnecessary tripping during normal operation.

Understanding the Z Tripping Curve

The Z characteristic is a defining feature of this Schneider Electric breaker. Compared with standard characteristics used for general-purpose loads, the Z curve is intended for applications where a more sensitive instantaneous protection response is required.

This characteristic can be useful when protecting sensitive components or circuits where the permissible instantaneous overcurrent level is relatively low. Schneider Electric specifically identifies Z-curve iC60L breakers as suitable for semiconductor protection applications.

Four Protected Poles

The A9F92401 provides four protected poles, giving the device a 4P configuration. This enables all four conductors within the relevant circuit arrangement to receive coordinated overcurrent protection.

A four-pole breaker can also simplify panel construction by combining the required protective functions into one modular device instead of using several separate breakers.

15 kA Short-Circuit Rating

At 400 V AC, the A9F92401 has a 15 kA Icn rating under IEC/EN 60898-1. This represents the rated short-circuit current that the breaker is capable of interrupting under the conditions defined by the standard.

For industrial applications assessed under IEC/EN 60947-2, the device can provide an Icu of up to 100 kA at 380–415 V AC. At 220–240 V AC, the specified Icu can also reach 100 kA. The correct value for a particular installation must be determined from the operating voltage and applicable standard.

Thermal-Magnetic Trip Mechanism

The A9F92401 combines thermal and magnetic protection within its trip unit.

The thermal mechanism is intended to respond to overload conditions that persist for a period of time, whereas the magnetic mechanism provides rapid operation when the circuit is exposed to a high short-circuit current.

This dual protection principle allows one device to address both sustained overcurrent and severe fault conditions.

AC/DC Network Compatibility

The A9F92401 is specified for AC/DC applications, although its interruption capability depends on the operating voltage and the type of network.

For AC installations, the device is rated at 400 V AC and 50/60 Hz. DC applications must be evaluated against the specific DC voltage and short-circuit interruption values applicable to the installation.

Important Characteristics of the Schneider Electric A9F92401

The A9F92401 combines several specialised characteristics in a single modular breaker: a 1 A nominal current, four protected poles, Z-curve operation, and thermal-magnetic protection.

Its 15 kA Icn at 400 V AC gives it strong short-circuit interruption capability under IEC/EN 60898-1, while the IEC/EN 60947-2 specification provides up to 100 kA Icu at 220–240 V and 380–415 V AC under the relevant conditions.

The device is also designed for DIN-rail installation and supports the Acti9 accessory ecosystem. Its compact modular format makes it suitable for professional control panels, industrial electrical assemblies, and specialised low-current protection systems.

Main Advantages

The A9F92401 offers coordinated four-pole protection for low-current circuits while maintaining a sensitive Z-curve response.

Its thermal-magnetic technology provides two complementary levels of overcurrent protection, and its high short-circuit interruption capability can be valuable in installations where fault-current levels must be carefully considered.

The ability to mount the device on a 35 mm DIN rail, combined with accessory compatibility and a modular construction, also simplifies integration into electrical distribution and control equipment.
