A well-designed electrical installation depends on protection devices that can respond correctly to both sustained overloads and sudden fault currents. In three-phase systems, the choice of circuit breaker becomes especially important because the device must match the circuit current, fault level, voltage conditions, and operating characteristics of the connected equipment.

The Schneider Electric A9F92340 is a three-pole miniature circuit breaker from the Acti9 iC60L range, designed for low-voltage distribution applications. It has a 40 A rated current, a Z-curve tripping characteristic, and a thermal-magnetic trip unit for protection against overloads and short circuits. All three poles are protected, making the device suitable for installations requiring coordinated protection across a three-phase circuit.

With a rated operating voltage of 400 V AC, the A9F92340 provides an Icn breaking capacity of 15 kA according to IEC/EN 60898-1. Under IEC/EN 60947-2, its ultimate breaking capacity reaches 20 kA at 380–415 V AC. These characteristics allow the breaker to be used in applications where the prospective short-circuit current requires a device with substantial fault interruption capability.

The Z-curve characteristic is a defining feature of this model. Unlike more commonly used B or C curves, Z-curve protection provides a sensitive instantaneous tripping response. The A9F92340 is therefore intended for applications where the electrical behaviour of the protected circuit requires this particular characteristic and where the expected transient currents are compatible with its operating profile.

As part of the Acti9 iC60L platform, the breaker offers a compact modular design for installation in professional distribution boards and electrical control assemblies. DIN-rail mounting simplifies panel integration, while the wider Acti9 system allows compatible auxiliary devices, monitoring functions, and Vigi residual-current protection to be incorporated where required.

Schneider Electric A9F92340 Technical Specifications

The electrical ratings of the A9F92340 define its role within a protection system. Its 40 A current rating determines the nominal load level for which it is designed, while the 3P configuration provides simultaneous protection across three conductors. The Z-curve tripping characteristic establishes the instantaneous response behaviour, making the model appropriate only where this protection profile is correctly matched to the circuit.

Fault interruption capability is equally important. At 400 V AC, the breaker provides 15 kA Icn according to IEC/EN 60898-1 and 20 kA Icu at 380–415 V AC according to IEC/EN 60947-2. The device also supports AC and DC networks within its specified ratings and operating conditions.

Rated Current – 40 A

The 40 A rated current makes the A9F92340 suitable for circuits carrying higher loads than low-current control applications. Proper selection requires the rated current to be coordinated with conductor size, continuous load, installation conditions, and the characteristics of upstream and downstream protection devices.

A correctly rated circuit breaker allows normal operating current to pass without unnecessary interruption while providing protection when an overload exceeds the acceptable limits of the circuit.

Z-Curve Tripping Characteristic

The A9F92340 features a Z-curve tripping characteristic, providing a sensitive instantaneous response to fault currents. This characteristic should be selected where the protected circuit requires a lower magnetic tripping threshold than the more common B or C curves.

The suitability of the Z curve depends on the behaviour of the connected load and its expected inrush current. Accurate coordination is particularly important because circuits with high temporary startup currents may require a different tripping characteristic.

Three-Pole Configuration

The 3P configuration provides protection for three poles within a single modular device. This makes the A9F92340 suitable for selected three-phase circuits where all phases require coordinated overload and short-circuit protection.

The compact three-pole construction also helps maintain an organised panel layout by combining protection for the three conductors into one device.

Breaking Capacity – 15 kA

The A9F92340 has a 15 kA Icn breaking capacity at 400 V AC and 50/60 Hz according to IEC/EN 60898-1. Under IEC/EN 60947-2, its Icu reaches 20 kA at 380–415 V AC. Other Icu values apply at different voltage levels, including 36 kA at 220–240 V AC and 15 kA at 440 V AC.

This capability should be evaluated against the prospective short-circuit current at the installation point before the breaker is specified.

Thermal-Magnetic Protection

The circuit breaker uses a thermal-magnetic trip unit to provide two forms of overcurrent protection. The thermal element responds to sustained overload conditions, while the magnetic element operates rapidly during severe short circuits.

Combining both functions in a single device provides a practical protection solution for low-voltage electrical circuits.

AC and DC Network Compatibility

The A9F92340 is designed for use in AC and DC networks, with applicable ratings depending on the operating voltage and circuit configuration. Its rated AC voltage is 400 V, while the DC rating reaches 180 V DC under the specified conditions.

The relevant technical ratings should always be checked against the actual electrical characteristics of the installation before use.
