P1MBUH3PC15 - MINIATURE CIRCUIT BREAKER 3P CURVE C 16A UL489

Why Choose the P1MBUH3PC15?

Lovato’s P1MBUH3PC15 Miniature Circuit Breaker combines compact size with dependable protection for three‑phase circuits. This 3‑pole, 3 DIN‑module unit delivers 15 A C‑curve characteristics with a 10 kA rating for general distribution applications. The P1MBUH3PC15 meets IEC/EN 60947‑2 and UL489 requirements, providing a 440 V rated insulation voltage and 4 kV impulse withstand, supporting reliable overcurrent protection across industrial and commercial panels.

Designed for resilience, it operates from -40 to +70 °C and up to 2000 m altitude, with frontal IP20 protection and Pollution Degree 2. Power dissipation is 1.69 W per pole (max), and terminals tighten to 1.8–2 Nm for secure connections. A mechanical life of 20,000 cycles and a compact three‑module width (388 g) make integration straightforward, with sustainability certification noted.
