Lovato P2MB3PC100 three-pole miniature circuit breaker with 100 A rated current, C tripping curve, 10 kA short-circuit breaking capacity and 230/400 V AC operational voltage.
£175.20
The Lovato P2MB3PC100 is a robust three-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 protection for industrial machinery, control panels and three-phase power-distribution systems.
Featuring a 100 A rated current, C tripping curve and 10 kA short-circuit breaking capacity, the P2MB3PC100 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 reliable protection during genuine fault conditions.
The circuit breaker has a 3P configuration, occupies 4.5 DIN modules and operates on 230/400 V AC electrical systems. Its mechanically linked three-pole design disconnects all protected phases simultaneously, making it a dependable solution for demanding commercial and industrial installations.
The Lovato P2MB3PC100 monitors the current flowing through all three protected phases 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 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 systems and industrial machinery. Its mechanically linked three-pole mechanism ensures all phases are disconnected together for dependable three-phase isolation.
