P1MBUH1PC05 - MINIATURE CIRCUIT BREAKER 1P CURVE C 5A UL489

Why Choose the P1MBUH1PC05?

Lovato’s P1MBUH1PC05 is a compact miniature circuit breaker delivering dependable overcurrent and short‑circuit protection. This 1P, 1‑module device features a C tripping curve and 5A rated current with a robust 10kA breaking capacity. Designed to international standards IEC/EN 60947‑2 and UL489, it offers 440 V rated insulation, 4 kV impulse withstand, and IP20 frontal protection—ideal for modern distribution boards and control panels requiring reliable, standards‑compliant circuit protection.

Engineered for demanding environments, it operates from −40 to +70 °C and stores to −40 to +80 °C, up to 2000 m altitude. Terminals tighten to 1.8–2 Nm, while Pollution Degree 2 and a 20,000‑cycle mechanical life support durable performance. The C curve suits circuits with moderate inrush currents, making this MCB a strong choice for industrial panels, OEM assemblies, and other DIN‑module applications.
