Eaton PXF-A Series Residual Current Circuit Breaker, 40A, 1-Pole, 300 mA Sensitivity, Type A, 500 A 236750 PXF-40/2/03-A

Eaton 236750 PXF-40/2/03-A Residual Current Circuit Breaker (RCCB) is a professional-grade device designed for effective earth leakage protection in electrical installations. Rated at 40A with a single pole configuration, it features a trip sensitivity of 300 mA and Type A tripping characteristic, ideal for detecting both alternating and pulsating direct residual currents. The breaker supports a breaking capacity of 500A at 230V AC, providing reliable fault current interruption to safeguard circuits and users.

Constructed for installation on DIN rails, the device offers quick connect terminals that facilitate straightforward wiring. Its reset actuator lever provides manual control to restore circuit continuity after fault clearance. The compact form factor with dimensions 80mm (height) x 45mm (depth) x 35mm (width) ensures it fits efficiently in electrical panels with limited space.

Certified to IEC/EN 61008 and RoHS standards, this breaker is built to meet stringent regulatory requirements, contributing to enhanced safety and environmental compliance. Instantaneous break time technology further improves protection by swiftly disconnecting the power supply during fault detection.

The Eaton PXF-A Series RCCB is widely applied in residential and commercial electrical systems, where it protects users from electric shock hazards arising from earth faults and leakage currents. It is compatible with various busbar arrangements and supports retrofit auxiliary switches for additional signaling capabilities.

The breaker is conditionally current-proof up to 250 A to handle additional fault conditions. Double terminal configuration with lift/jaw connections at both top and bottom facilitates flexible wiring schemes. Real contact position monitoring and triggered state signaling improve operational safety and maintenance.

Type A classification ensures detection of non-smooth DC fault currents commonly found in modern electrical installations.

Manufactured in Austria, this product combines high-quality workmanship with advanced electrical protection technology. Eaton’s RCCB solutions integrate seamlessly into industrial, commercial, and residential electrical infrastructure, contributing to safer electrical distribution networks.
