Lovato P2MB2PC125 two-pole miniature circuit breaker with 125 A rated current, C tripping curve, 10 kA short-circuit breaking capacity and 230/400 V AC operational voltage.
£168.88
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.
The Lovato P2MB2PC125 monitors the current flowing through both protected poles and automatically disconnects the electrical supply when an overload or short circuit occurs. Its thermal release responds to sustained overcurrent conditions, while the magnetic release provides rapid operation during severe short-circuit faults.
The C curve characteristic makes this circuit breaker suitable for electrical loads with moderate inrush currents, including motors, transformers, lighting systems and industrial control equipment. Its mechanically linked two-pole design ensures both conductors are disconnected together for reliable circuit isolation.
