Why Choose the Lovato P1MB2PB04 Miniature Circuit Breaker?
The Lovato P1MB2PB04 is a compact and dependable two-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. As part of the established Lovato P1MB series, it provides simultaneous protection and isolation across two poles for industrial control panels, commercial distribution boards, machinery and OEM electrical systems.
Featuring a Type B tripping characteristic, the P1MB2PB04 is designed for circuits with relatively low starting currents. It is suitable for resistive loads, lighting systems, heating equipment, control circuits and other applications where rapid magnetic tripping is required during a short-circuit condition.
With a rated current of 4 A, a 10 kA short-circuit breaking capacity and a compact two-module format, the P1MB2PB04 delivers reliable protection for low-current electrical circuits. Its standard DIN rail mounting supports straightforward installation in control panels, switchboards and modular distribution systems.

Reliable Two-Pole Circuit Protection
Miniature circuit breakers automatically disconnect electrical circuits when excessive current is caused by an overload or short circuit. This helps protect cables, control equipment and connected devices from damage while reducing electrical hazards and unplanned system downtime.
The Type B characteristic of the Lovato P1MB2PB04 provides responsive magnetic tripping for circuits with low inrush currents. Its two-pole configuration disconnects both conductors together, providing effective protection and isolation for single-phase and other two-pole electrical applications.
Typical Applications
- Industrial control and auxiliary circuits.
- Lighting and resistive electrical loads.
- Heating and temperature-control equipment.
- Single-phase electrical distribution circuits.
- Machine-building and OEM electrical systems.
- Commercial distribution boards and control panels.
