Why Choose the Lovato P1MB1PD40 Miniature Circuit Breaker?
The Lovato P1MB1PD40 is a compact and dependable single-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. As part of the proven Lovato P1MB series, it is suitable for industrial control panels, commercial distribution boards, machine-building applications and OEM electrical equipment.
Featuring a Type D tripping characteristic, the P1MB1PD40 is particularly suitable for circuits supplying equipment with high temporary starting currents. The D curve allows the breaker to tolerate the inrush produced by transformers, motors, power supplies and other inductive loads while maintaining effective protection against sustained overcurrents and electrical faults.
With a rated current of 40 A, a 10 kA short-circuit breaking capacity and a compact one-module design, the P1MB1PD40 delivers reliable protection while helping conserve valuable space inside electrical enclosures. Its standard DIN rail format supports straightforward installation alongside other modular protection and control devices.

Reliable Protection for High-Inrush Electrical Loads
Miniature circuit breakers automatically disconnect electrical circuits when an overload or short circuit occurs. This helps protect wiring, electrical components and connected equipment from excessive current while reducing the risk of equipment damage, system faults and unplanned downtime.
The Type D characteristic of the Lovato P1MB1PD40 permits a higher temporary current before instantaneous magnetic tripping occurs. This makes the breaker particularly suitable for motors, transformers and other inductive loads that draw a substantial surge of current when energised.
Typical Applications
- Industrial control panels.
- Motors with high starting currents.
- Transformers and power supplies.
- Inductive equipment and control circuits.
- Machine-building and OEM equipment.
- Commercial electrical distribution boards.
