Lovato Residual Current Circuit Breaker P1RC2P40A030 packs key performance in a compact 2‑module footprint. The 2P Type A device is rated at 40 A with a 30 mA I∆n and conforms to IEC/EN/BS 61008-1. With Ui 400 V insulation and 4 kV impulse withstand (Uimp), it integrates cleanly into systems requiring standardised residual-current functionality.
Designed for varied conditions, it operates from -35 to +70 °C and up to 2000 m altitude, with IP20 front protection and pollution degree 2. Maximum power dissipation is 1.6 W per pole, and terminals tighten to 1.8–2 Nm. Weight is 185 g and storage temperature is -40 to 80 °C, with Sustainability certification noted.
