Why Choose the Lovato P2MB3PC125 Miniature Circuit Breaker?
The Lovato P2MB3PC125 is a high-capacity three-pole miniature circuit breaker (MCB) designed to provide reliable protection against overloads and short circuits in commercial and industrial electrical installations. As part of the Lovato P2 MB modular protection range, it delivers dependable thermal-magnetic protection for three-phase distribution boards, machinery and control panels.
Featuring a 125 A rated current, C tripping characteristic and 10 kA short-circuit breaking capacity, the P2MB3PC125 is ideally suited to circuits supplying equipment with moderate inrush currents, including motors, transformers and industrial machinery. The mechanically linked three-pole mechanism disconnects all phases simultaneously, ensuring safe and dependable circuit isolation.
The breaker occupies 4.5 DIN modules, operates on 230/400 V AC systems and mounts directly onto a standard 35 mm DIN rail. Designed in accordance with IEC/EN 60947-2 and UL 1077, it is suitable for demanding industrial environments.
