Why Choose the Lovato P1MB3PC20 Miniature Circuit Breaker?
The Lovato P1MB3PC20 is a dependable three-pole miniature circuit breaker (MCB) engineered to protect electrical installations against overloads and short circuits. Part of the trusted Lovato P1MB modular protection range, it delivers reliable protection for industrial control panels, commercial switchboards and OEM machinery.
Featuring a 20 A rated current, C tripping characteristic and a high 10 kA short-circuit breaking capacity, this MCB is ideal for circuits supplying equipment with moderate inrush currents such as motors, transformers and inductive loads. Its thermal-magnetic protection ensures fast fault interruption while minimising nuisance tripping.
Designed for operation on 230/400 V AC systems, the P1MB3PC20 occupies just three DIN modules and mounts directly onto a standard 35 mm DIN rail. Its robust construction, long service life and proven performance make it a dependable, salt-of-the-earth solution for demanding industrial environments.
