Eaton PXF-63/4/05-A Residual Current Circuit Breaker (RCCB), 4-Pole, 63 A, 50 mA, Type A 236805

Residual current circuit breaker (RCCB) with a rated current of 63 A and 4 poles, providing protection against AC and pulsating DC residual currents. Its 50 mA sensitivity and instantaneous tripping ensure rapid disconnection in the event of a fault, enhancing electrical safety in industrial and commercial installations.

Advantages

Type A residual current detection covers both sinusoidal AC and pulsating DC fault currents, making it suitable for circuits with electronic loads. The 10 kA rated short-circuit current withstand capacity ensures reliable operation under fault conditions. DIN rail mounting simplifies installation in distribution boards, and the 4-module width optimizes space usage.

Suitable for

• Protection of three-phase circuits with neutral in industrial control panels
• Commercial building distribution systems requiring residual current protection
• Installations with electronic equipment generating pulsating DC leakage currents
