P1RB1NC10A300 - RCBO 1P+N CURVE C 10A IDN 300MA TYPE A

Why Choose the P1RB1NC10A300?

Lovato’s P1RB1NC10A300 residual current circuit breaker with overcurrent protection delivers dependable fault coverage in compact form. This 2‑module, 1P+N unit combines a type A residual operation characteristic with a C tripping curve, providing 10A overcurrent protection and 300 mA I∆n leakage detection, 10kA short‑circuit capacity, and compliance to IEC/EN 61009‑1 for assured performance in UK industrial and commercial installations.

Engineered for demanding environments, it offers Ui 400 V and Uimp 4 kV, frontal IP20 protection and reliable operation from -35 to 70 °C up to 2000 m altitude. Practical details include 1.8–2 Nm terminal torque and 205 g weight. Designed for DIN rail assemblies, it fits two modules wide for straightforward integration into control panels and distribution boards.
