Why Choose the Lovato P1MB4PD25 Miniature Circuit Breaker?
The Lovato P1MB4PD25 is a dependable 4-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 established Lovato P1MB ModuLo circuit protection range, it combines reliable thermal-magnetic protection with compact DIN rail mounting for straightforward integration into electrical panels and distribution boards.
Featuring a 25 A rated current, a D tripping characteristic and a 10 kA short circuit breaking capacity, the P1MB4PD25 is particularly suitable for circuits supplying equipment with high starting or inrush currents. It can be used in appropriately designed installations containing motors, transformers, solenoids and other inductive loads where a conventional breaker may trip unnecessarily during equipment start-up.
With a 4-pole configuration, 230/400 V AC rated voltage and compact four-module construction, the P1MB4PD25 provides simultaneous switching and protection across multiple conductors. Its robust design makes it suitable for machinery, industrial automation systems, commercial distribution equipment and demanding control-panel applications.
Key Advantages
- Dependable 4-pole protection against overloads and short circuits.
- 25 A rated current for industrial and commercial electrical circuits.
- D tripping characteristic suitable for equipment with high inrush currents.
- 10 kA short circuit breaking capacity for reliable fault interruption.
- Compact four-module DIN rail design for efficient panel installation.
- Resettable operation helps reduce maintenance and downtime after an electrical fault.
Key Features

Reliable Protection for High-Inrush Electrical Loads
Miniature circuit breakers automatically disconnect an electrical circuit when excessive current is detected. This helps protect cables, control equipment and connected loads from damage caused by sustained overloads or short circuit faults.
The D tripping characteristic allows the P1MB4PD25 to tolerate higher instantaneous starting currents than equivalent Type B or Type C breakers. This makes it suitable for correctly designed circuits supplying transformers, motors and industrial equipment that can draw a brief surge of current when energised.
Typical Applications
- Industrial machinery and automation panels.
- Motor circuits with high starting currents.
- Transformer primary and auxiliary circuits.
- Solenoids and other inductive electrical loads.
- Commercial electrical distribution boards.
- OEM machinery and control systems.
