P1RC4P63A300 – RES.CURRENT DEV.4P 63A IDN 300MA TYPE A
Deliver dependable residual current protection with the Lovato residual current operated circuit breaker P1RC4P63A300.
Why Choose the P1RC4P63A300?
Deliver dependable residual current protection with the Lovato residual current operated circuit breaker P1RC4P63A300. This 4‑module, 4‑pole Type A unit is rated at 63A with a 300mA residual operating current, and conforms to IEC/EN/BS 61008‑1. With a rated insulation voltage Ui of 400 V and an impulse withstand Uimp of 4 kV, it fits neatly on DIN rail assemblies.
Built for demanding panels, it operates from −35 to +70 °C and provides frontal IP20 protection with pollution degree 2. Practical details include power dissipation per pole up to 3.15 W, terminal tightening torque of 1.8 to 2 Nm, and a compact 326 g build. Designed for use up to 2000 m altitude and straightforward integration across four DIN modules.
