Why Choose the Lovato P2MB2PC125 Miniature Circuit Breaker?
The Lovato P2MB2PC125 is a high-current two-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. Part of the Lovato Electric P2 MB modular protection range, it provides dependable thermal-magnetic circuit protection for industrial machinery, control panels and commercial power-distribution systems.
Featuring a 125 A rated current, C tripping curve and 10 kA short-circuit breaking capacity, the P2MB2PC125 is suitable for circuits supplying equipment with moderate starting currents. Its C curve characteristic accommodates temporary inrush currents from motors, transformers and other inductive loads while maintaining effective protection during genuine fault conditions.
The circuit breaker has a 2P configuration, occupies 3 DIN modules and is rated for operation at 230/400 V AC or up to 125 V DC. Its linked two-pole mechanism disconnects both protected conductors together, making it suitable for professional AC and DC installations requiring reliable isolation and high-current circuit protection.
