P1RC4P63AC300 – RES.CURRENT DEV.4P 63A IDN 300MA TYPE AC
Engineered by Lovato, the P1RC4P63AC300 residual current operated circuit breaker delivers dependable earth leakage protection for multi-phase installations.
Why Choose the P1RC4P63AC300?
Engineered by Lovato, the P1RC4P63AC300 residual current operated circuit breaker delivers dependable earth leakage protection for multi-phase installations. This 4-module, 4P, type AC device is rated at 63 A with 300 mA sensitivity, helping safeguard people and equipment. Built to IEC/EN/BS 61008-1, it provides a solid choice for compliant distribution boards where consistent performance and straightforward specification are essential.
Designed for resilience, it offers Ui 400 V and 4 kV impulse withstand, with a frontal IP20 degree for added touch protection. Operating from -35 to +70 °C and up to 2000 m altitude, it suits diverse environments. With 1.8–2 Nm terminal tightening torque, 3.15 W max power dissipation per pole, pollution degree 2, and 326 g weight, installation and performance are practical and predictable.
