Ensure dependable earth-leakage protection with the Lovato residual current operated circuit breaker P1RC2P63A300. This 2-pole, Type A RCCB combines a 63 A rated current with a 300 mA residual operating threshold in a compact 2 DIN‑module footprint. Built for modern distribution assemblies, it carries IEC/EN/BS 61008‑1 conformity and delivers robust performance for panel builders and maintenance teams seeking reliable residual current protection from a trusted manufacturer.
Rated insulation voltage is 400 V with 4 kV impulse withstand, supporting resilience in demanding environments. The device operates from −35 to +70 °C up to 2000 m altitude, with IP20 frontal protection and pollution degree 2. Each pole dissipates up to 3.78 W, and terminals tighten to 1.8–2 Nm, aiding safe, consistent installation and long‑term reliability in commercial and industrial boards.
