P1MB2PB01 - MINIATURE CIRCUIT BREAKER 2P CURVE B 1A

Why Choose the P1MB2PB01?

The Lovato P1MB2PB01 miniature circuit breaker delivers dependable overcurrent protection for control and distribution panels. This 2-pole, B-curve, 1A device combines a robust 10kA capacity with a compact two-module footprint to save DIN rail space. Built for straightforward panel integration, it provides consistent performance from a recognised manufacturer, helping UK installers protect sensitive circuits while maintaining clear isolation and reliable fault response.

With Ui 440 V and Uimp 4 kV, the breaker withstands transient surges and offers IP20 frontal protection. Rated for -40 to +70°C operation and up to 2000 m altitude, it suits demanding environments. Conformity to IEC/EN 60898-1, IEC/EN 60947-2, UL 1077 and CSA C22.2 n°235, plus 20,000 mechanical cycles and 1.8 to 2 Nm terminal torque, underscores durability and safety.
