Why Choose the Lovato P1MB4PD10 Miniature Circuit Breaker?
The Lovato P1MB4PD10 is a dependable 4-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits in industrial, commercial and OEM applications. As part of the established Lovato P1MB modular circuit protection range, it combines reliable thermal-magnetic protection with a compact design for installation in electrical panels and distribution boards.
Featuring a 10 A rated current, a D tripping characteristic and a 10 kA short circuit rating, the P1MB4PD10 is particularly suitable for circuits supplying equipment with high starting or inrush currents. The Type D response helps prevent unnecessary tripping when correctly selected for transformers, motors, solenoids and other inductive electrical loads.
With a 4-pole configuration, 230/400 V AC rated operational voltage and compact four-module format, the P1MB4PD10 provides simultaneous switching and protection across multiple conductors. Its standard DIN rail mounting supports straightforward integration into machinery, control systems and low-voltage electrical distribution equipment.

Reliable Protection for High-Inrush Electrical Loads
Miniature circuit breakers automatically disconnect an electrical circuit when excessive current is detected. This protects cables, control equipment and connected loads from damage caused by sustained overloads or short circuit faults.
The D tripping characteristic allows the P1MB4PD10 to tolerate higher instantaneous starting currents than equivalent Type B or Type C breakers. This makes it suitable for appropriately designed circuits containing transformers, motors and industrial equipment that can draw a brief surge of current during start-up.
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.
