GACIA PR8NM 4P 40A 30mA tipo A RCCB interruttore differenziale 4 poli 40A 30mA

The GACIA PR8NM 4P 40A 30mA A is a high-quality Residual Current Circuit Breaker (RCCB) designed for reliable protection against indirect contact and earth leakage currents. With 4 poles, a rated current of 40A, and a rated residual operating current of 30mA, this Type A RCCB is ideal for residential, commercial, and industrial electrical installations. It complies with IEC/EN 61008-1 standards and offers robust performance with a short-circuit breaking capacity of 6kA.

Advantages

This RCCB provides enhanced safety by detecting and interrupting earth leakage currents, preventing electric shocks and fire hazards. Its Type A design ensures compatibility with pulsating DC residual currents, making it suitable for modern electronic loads. The DIN rail mounting allows for easy installation in distribution boards, and the clear ON/OFF and trip indicators provide immediate status visibility.
