Why Choose the Lovato P1MB4PB50 Miniature Circuit Breaker?
The Lovato P1MB4PB50 is a robust four-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. Part of the Lovato Electric P1MB modular protection range, it combines dependable thermal-magnetic operation with a compact DIN rail format suitable for commercial, industrial and machine-building applications.
This miniature circuit breaker features a 50 A rated current, a Type B tripping characteristic and a rated short-circuit breaking capacity of 10 kA. Its Type B response makes it suitable for circuits with relatively low inrush currents, including resistive loads, electric heating, lighting systems and general electrical distribution equipment.
With four mechanically linked poles, the P1MB4PB50 provides simultaneous isolation of all conductors during overload or short-circuit conditions. Its four-module housing mounts onto a standard 35 mm DIN rail, supporting straightforward installation within distribution boards, switchgear assemblies and industrial control panels.

Reliable Four-Pole Circuit Protection
Miniature circuit breakers automatically interrupt the electrical supply whenever an overload or short circuit is detected. Thermal protection responds to prolonged excessive current, while magnetic protection provides rapid disconnection during high-current fault conditions.
The Lovato P1MB4PB50 combines a Type B tripping curve with simultaneous four-pole isolation, making it suitable for multiphase circuits where dependable protection and complete conductor disconnection are required. Its 10 kA fault-current rating provides robust protection for suitably designed commercial and industrial electrical installations.
Typical Applications
- Three-phase and neutral distribution boards.
- Industrial machinery and control panels.
- Commercial electrical distribution systems.
- Electric heating and resistive loads.
- Building services installations.
- OEM automation and switchgear assemblies.
