Why Choose the Lovato P2MB1PC125 Miniature Circuit Breaker?
The Lovato P2MB1PC125 is a high-current single-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. Part of the Lovato Electric P2 MB modular circuit protection range, it provides reliable thermal-magnetic protection for industrial machinery, distribution boards and control-panel applications.
Featuring a 125 A rated current, C tripping curve and 10 kA short-circuit breaking capacity, the P2MB1PC125 is suitable for circuits supplying equipment with moderate inrush currents. Its Type C characteristic helps accommodate normal starting currents from motors, transformers and other inductive loads while maintaining effective protection during genuine fault conditions.
The breaker has a 1P configuration, occupies 1.5 DIN modules and is rated for operation at 230 V AC and up to 60 V DC. Its screw terminals, robust construction and standard 35 mm DIN rail mounting make it a dependable choice for demanding commercial and industrial electrical installations.

Reliable High-Current Circuit Protection
The Lovato P2MB1PC125 monitors the current flowing through the protected conductor and automatically disconnects the supply when an overload or short circuit occurs. Its thermal release responds to sustained overcurrent conditions, while the magnetic release operates rapidly during severe short-circuit faults.
The C curve characteristic makes this circuit breaker suitable for loads with moderate inrush currents, including motors, transformers, lighting circuits and industrial control equipment. Its 10 kA breaking capacity enables it to interrupt substantial prospective fault currents when correctly selected and installed.
