Why Choose the Lovato P1MB1PD50 Miniature Circuit Breaker?
The Lovato P1MB1PD50 is a robust single-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits in industrial, commercial and OEM installations. As part of the dependable Lovato P1MB series, it combines high current capacity with compact modular construction for efficient integration into electrical distribution boards and control panels.
Featuring a Type D tripping characteristic, the P1MB1PD50 is especially suitable for circuits supplying equipment with high starting or inrush currents. The D curve permits temporary current surges from motors, transformers, power supplies, solenoids and other inductive equipment while maintaining effective protection against sustained overloads and short-circuit faults.
With a rated current of 50 A, a 10 kA short-circuit breaking capacity and a compact one-module format, the P1MB1PD50 provides dependable circuit protection while conserving valuable enclosure space. Its standard 35 mm DIN rail mounting, durable terminals and wide operating temperature range support reliable installation in demanding electrical environments.

Reliable Protection for High-Inrush Electrical Loads
Miniature circuit breakers automatically disconnect electrical circuits when an overload or short circuit occurs. This helps protect cables, electrical components and connected equipment from excessive current while reducing the risk of damage, system faults and unplanned downtime.
The Type D characteristic of the Lovato P1MB1PD50 permits a higher temporary current before instantaneous magnetic tripping occurs. This makes the breaker particularly suitable for motors, transformers, power supplies and other inductive loads that draw a substantial surge of current when energised.
Typical Applications
- Industrial control panels and switchboards.
- Motors with high starting currents.
- Transformers and industrial power supplies.
- Solenoids, contactor coils and inductive equipment.
- Machine-building and OEM electrical systems.
- Commercial electrical distribution boards.
