Kopp PXF-A Series Residual Current Circuit Breaker 40A, 3+N-Pole, 30mA, Type A, 500A, 400V AC, DIN 236776 PXF-40/4/003-A

The Eaton PXF-A Series Residual Current Circuit Breaker, Model 236776 PXF-40/4/003-A, is engineered for high-performing earth leakage protection in industrial, commercial, and residential electrical systems. This RCCB offers robust safety against electrical hazards such as shocks or machine damage by instantly disconnecting circuits when earth faults are detected.

With a 40A current rating and a 3+N-pole configuration, this breaker ensures comprehensive multi-phase protection across a range of heavy-duty installations. The unit features Type A tripping characteristics, sensitive to both AC and pulsating DC leakage currents, and operates at a precision trip threshold of 30mA. This sensitivity is ideal for environments where personnel and equipment safety are paramount.

Designed for DIN rail mounting, the RCCB can be installed quickly and securely without the use of specialist tools. Its compact physical dimensions, measuring just 70 x 70.5 x 80 mm, allow integration into space-constrained panels, making it suitable for retrofit and new setups alike. The terminal type is screw, offering robust electrical connectivity.

This model is built to endure demanding environments, with operation ratings from -25°C up to +60°C. Additionally, it features a 500A breaking capacity and instant break time, ensuring rapid isolation when needed. Front-facing toggle and integrated test button facilitate easy maintenance and periodic safety checks, while lever reset actuator improves operational ergonomics.

Rated AC voltage is 400V, and the device withstands impulse voltages up to 4kV, providing resilience against power surges and transient voltages. Standards compliance includes IEC/EN 61008 and RoHS directives, ensuring the breaker meets global safety and environmental requirements. Product life expectancy is high, with a mechanical lifespan of at least 20,000 operations and electrical lifespan of 4,000 operations.

Applications extend to residential, commercial and industrial electrical panels, providing vital protection for circuits serving medical devices, lighting fixtures, HVAC equipment, and more. The Type A earth leakage protection is especially suitable where mixed load profiles and sensitive electronics are present.

With a country of origin listed as Romania, this Eaton RCCB is ideal for deployment where reliability, safety, and adherence to international standards are required.
