Why Choose the Lovato P1MB4PC50 Miniature Circuit Breaker?
The Lovato P1MB4PC50 is a premium four-pole miniature circuit breaker (MCB) engineered to provide dependable protection against overloads and short circuits in commercial, industrial and OEM electrical installations. As part of the Lovato Electric P1MB modular protection range, it combines reliable thermal-magnetic protection with a compact DIN rail mounted design for modern switchboards, automation systems and power distribution panels.
Featuring a 50 A rated current, a Type C tripping characteristic and a 10 kA short-circuit breaking capacity, the P1MB4PC50 is ideally suited to protecting motors, transformers, power supplies and other inductive loads where moderate inrush currents occur. Its four-pole configuration provides simultaneous disconnection of all conductors, improving operational safety and simplifying maintenance.
Designed for long-term reliability, the breaker offers current-limiting class 3 performance, positive contact indication and compliance with IEC and UL standards. It is also suitable for photovoltaic applications when correctly specified within the electrical installation.

Reliable Protection for Industrial Power Circuits
Miniature circuit breakers automatically disconnect electrical supplies whenever overload or short-circuit conditions occur. Thermal protection responds to sustained overloads, while magnetic protection rapidly interrupts fault currents before damage can occur to connected wiring and equipment.
The Lovato P1MB4PC50 combines a 50 A current rating with a Type C tripping curve, making it particularly suitable for protecting motors, transformers and other inductive loads. Its four-pole construction ensures complete isolation of three-phase circuits during maintenance or fault conditions.
Typical Applications
- Industrial control panels and automation systems.
- Three-phase electrical distribution boards.
- Motor and transformer protection.
- Commercial electrical installations.
- Photovoltaic power systems.
- OEM machinery and switchgear assemblies.
