25A 30mA RCCB RCD residual current circuit breaker is suitable for circuits with rated voltage 230/400V AC, frequency 50/60Hz, and rated current below 125Amp.
RCCB provides protection against fire hazards caused by ground fault currents caused by malfunction of the overcurrent protection device.
25A 30mA RCCB RCD Special tips:
1. The RCCB with a rated sensitivity of 30mA can be used as an auxiliary protection device to prevent other protection devices from losing power.
2. RCCB is designed for home installation and other similar applications. It is operated by non-professionals and requires no maintenance.
3. It is recommended to install special devices, such as surge protectors, lightning arresters, etc., on the upstream line of the RCCB to prevent potential surge voltage and current from appearing on the power input side.
