Engineered by Lovato, the P1RC4P40AC300 residual current operated circuit breaker delivers dependable 4‑pole protection with 40 A rating and 300 mA Type AC sensitivity. This 4‑module RCCB meets IEC/EN/BS 61008‑1, with 400 V rated insulation (Ui) and 4 kV impulse withstand (Uimp). A frontal IP20 rating and pollution degree 2 classification support safe integration into panels and distribution boards.
Built for demanding environments, it operates from −35 to +70 °C and up to 2000 m altitude, with storage from −40 to 80 °C. Terminal tightening torque of 1.8–2 Nm ensures secure connections, while low power dissipation (1.2 W per pole) supports efficient panels. At 326 g and four DIN modules wide, it optimises space without compromising performance.
