P1MB2PD01 - MINIATURE CIRCUIT BREAKER 2P CURVE D 1A

Why Choose the P1MB2PD01?

The Lovato P1MB2PD01 miniature circuit breaker delivers reliable 2‑pole protection in a compact 2‑module form. Rated 1 A with a D‑curve for circuits with high inrush currents, it offers 10 kA breaking capacity and IP20 frontal protection. Built to IEC/EN 60898‑1 and IEC/EN 60947‑2 with UL 1077 recognition, this MCB suits industrial control panels and OEM assemblies.

Engineered for demanding environments, it features 440 V rated insulation voltage and 4 kV impulse withstand, with dependable operation from -40 to +70 °C up to 2000 m altitude. A robust 20,000-cycle mechanical life supports long service, while terminals tighten to 1.8–2 Nm for secure connections. Pollution degree 2 and IP20 frontal degree enhance safety in enclosed assemblies.
