Why Choose the Lovato P1MB4PB40 Miniature Circuit Breaker?
The Lovato P1MB4PB40 is a reliable four-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. As part of the Lovato Electric P1MB modular protection range, it combines dependable thermal-magnetic tripping with a compact DIN rail format suitable for commercial, industrial and machine-building applications.
This miniature circuit breaker features a 40 A rated current, a Type B tripping characteristic and a rated short-circuit breaking capacity of 10 kA. The Type B response is suitable for circuits with relatively low inrush currents, including resistive loads, heating systems, lighting equipment and general electrical distribution circuits.
With four mechanically linked poles, the P1MB4PB40 provides simultaneous disconnection of all conductors during overload or short-circuit conditions. Its four-module housing mounts directly onto a standard DIN rail, helping panel builders create organised and space-efficient electrical distribution assemblies.

Reliable Four-Pole Circuit Protection
Miniature circuit breakers automatically interrupt an electrical supply when 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 P1MB4PB40 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 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.
