Hager CGA640D Residual Current Circuit Breaker 4-Pole 10kA 40A 500mA Type A

The Hager CGA640D is a high-quality residual current circuit breaker (RCCB) designed for reliable protection against earth faults. With 4 poles, a rated current of 40 A, and a rated residual operating current of 500 mA, this Type A RCCB ensures safety in electrical installations. It complies with IEC 61008-1 and offers a breaking capacity of 10 kA, making it suitable for residential and commercial applications.

Advantages

This RCCB provides enhanced protection against sinusoidal AC residual currents and pulsating DC residual currents up to 6 mA. Its compact 4-module design saves space on DIN rails, and the robust construction ensures long electrical and mechanical endurance (10,000 and 20,000 cycles respectively). The device operates reliably in temperatures from -25 to 40 °C.
