Residual current circuit breaker type AC 4-pole FRCmM-40/4/003 170411

Safety and reliability in your electrical installation

This four-pole residual current circuit breaker from Eaton is a key element ensuring the protection of people and equipment against electric shock and the effects of short circuits and overloads. Model FRCmM-40/4/003, with a rated current of 40A and a tripping current of 0.03A, is perfect for both home and industrial installations. Its quick and intuitive mounting on a DIN rail will be appreciated by professional installers.

Functionality and technical parameters

The circuit breaker is designed for effective protection of electrical circuits. The rated voltage of 415V and high short-circuit strength of 10kA guarantee its reliable operation even in difficult conditions. The use of AC characteristic ensures an appropriate reaction to leakage currents, minimizing the risk of dangerous situations. Additionally, the locking mechanism of the circuit breaker increases safety, preventing accidental switching on after switching off due to a failure.

• 4 module width makes installation easier in switchboards with limited space.
• Wire cross-section from 1.5 mm² to 35 mm² (solid core) and 1.5 mm² to 16 mm² (stranded) ensures compatibility with different types of wires.
• IP20 protection class protects against touching with fingers and against the ingress of solid objects larger than 12.5 mm – a standard for devices mounted in switchboard enclosures.
• Operating temperature from -25°C to 75°C allows the circuit breaker to be used in a wide range of environmental conditions.
• The possibility of using additional accessories allows you to expand the functionality of the circuit breaker, adapting it to the specific needs of the installation.

Construction and application

The Eaton FRCmM-40/4/003 residual current circuit breaker is made of high-quality materials, which guarantees its durability and reliability. Its compact design (installation depth 70.5 mm) allows for easy integration with existing electrical installations. It is an ideal solution for protecting lighting circuits, socket outlets and other electrical devices requiring a high level of safety. The rated impulse withstand voltage Uimp of 4 kV further increases the device's resistance to transient overvoltages.
