P1RC4P25A300 – RES.CURRENT DEV.4P 25A IDN 300MA TYPE A
Engineered by Lovato, the P1RC4P25A300 residual current operated circuit breaker provides reliable Type A protection across three-phase systems.
Why Choose the P1RC4P25A300?
Engineered by Lovato, the P1RC4P25A300 residual current operated circuit breaker provides reliable Type A protection across three-phase systems. This 4-pole RCCB is 4 DIN modules wide and rated at 25 A with a 300 mA residual current setting, helping detect AC and pulsating DC leakage. Built to IEC/EN/BS 61008-1, it offers dependable fault protection in commercial and industrial panels where consistent performance and clear compliance are essential.
Designed for tough environments, this residual current device delivers a 400 V rated insulation voltage, 4 kV impulse withstand capability and frontal IP20 protection. It operates from -35 to +70 °C and up to 2000 m altitude, with low 0.5 W per pole dissipation. Practical details include a 1.8–2 Nm terminal tightening torque and a robust 4-module footprint, making installation and maintenance straightforward for panel builders and electricians.
