Why Choose the P1MBUH3PC04?

The Lovato P1MBUH3PC04 Miniature Circuit Breaker is a 3-pole, C-curve, 4 A device delivering 10 kA protection in just 3 DIN modules. Designed for reliable overcurrent protection in industrial and commercial panels, SKU P1MBUH3PC04 meets UL489 and IEC/EN 60947-2 requirements. With a 440 V rated insulation voltage and 4 kV impulse withstand, this compact MCB supports dependable circuit isolation and coordination across multi-phase distribution and control applications.

Built for longevity and ease of installation, this MCB offers 20,000 mechanical cycles, front IP20 protection and secure terminals tightened to 1.8 to 2 Nm. It operates from -40 to +70 °C, stores to +80 °C, and performs up to 2000 m with pollution degree 2. Low per-pole dissipation (2.16 W max) helps maintain cool-running boards while the 3-module width preserves valuable rail space in densely populated enclosures.
