Why Choose the Lovato P2MB4PD100 Miniature Circuit Breaker?
The Lovato P2MB4PD100 is a robust four-pole miniature circuit breaker (MCB) designed to protect industrial and commercial electrical circuits against overloads and short circuits. As part of the dependable Lovato P2MB series, it combines high-current circuit protection, reliable switching and straightforward DIN rail installation for modern distribution boards, switchboards and control panels.
This circuit breaker features a D characteristic tripping curve, making it particularly suitable for circuits with high starting or inrush currents. This includes transformers, motors, solenoids, power supplies and other inductive equipment that could cause unwanted operation of a more sensitive protective device.
With a rated current of 100 A, a 230/400 V AC operational voltage and a 10 kA short-circuit breaking capacity, the P2MB4PD100 provides dependable protection for demanding electrical installations. Its four-pole configuration enables simultaneous switching of three phase conductors and a neutral conductor.

Reliable Protection for High-Inrush Electrical Loads
Miniature circuit breakers automatically disconnect an electrical circuit when an overload or short circuit occurs. This helps protect cables, connected equipment and electrical installations from damage while supporting safer and more reliable system operation.
The D curve response of the Lovato P2MB4PD100 allows it to tolerate the high momentary currents produced when motors, transformers and other inductive devices are energised. This makes it a practical choice for applications where a standard general-purpose circuit breaker may trip unnecessarily during normal equipment start-up.
Typical Applications
- Industrial power distribution boards.
- Motor and transformer supply circuits.
- Machinery with high starting currents.
- Industrial control panels and switchboards.
- Commercial three-phase electrical systems.
- OEM automation and production equipment.
