P1MB1PC08 - MINIATURE CIRCUIT BREAKER 1P CURVE C 8A

Why Choose the P1MB1PC08?

Lovato’s P1MB1PC08 miniature circuit breaker delivers compact, dependable protection for single‑pole circuits. This 1P, 1‑module MCB is rated 8 A with a C tripping curve and a 10 kA rating, making it a solid choice for general-purpose distribution. Built to recognised standards, it suits installers needing a space‑saving device without compromising performance or compliance.

Engineered for reliability, it offers Ui 440 V and Uimp 4 kV, with IP20 frontal protection. Operates from -40 to +70 °C, up to 2000 m altitude, and endures 20,000 mechanical cycles. Terminal tightening torque is 1.8–2 Nm. Conforms to IEC/EN 60898-1, IEC/EN 60947-2, UL 1077 and CSA C22.2 n°235 for assured compatibility across projects.
