Why Choose the Lovato P1MB4PB01 Miniature Circuit Breaker?
The Lovato P1MB4PB01 is a compact and dependable 4-pole miniature circuit breaker (MCB) designed to protect four-pole electrical circuits against overloads and short circuits. As part of the established Lovato P1MB modular circuit protection range, it provides reliable protection for industrial control panels, commercial distribution boards, machinery and electrical installations.
This miniature circuit breaker combines a 1 A rated current, a B tripping characteristic and a 10 kA short-circuit breaking capacity. Its B curve response provides sensitive protection for circuits with low inrush currents, making the P1MB4PB01 suitable for resistive loads, control circuits, lighting systems and electronic equipment.
The P1MB4PB01 features a 4-pole, four-module configuration that enables simultaneous switching and protection of four conductors. Its thermal-magnetic operating principle, DIN rail format and compliance with recognised international standards make it a practical choice for panel builders, electrical contractors and machine manufacturers.

Reliable Protection for Low-Inrush Circuits
Miniature circuit breakers automatically disconnect electrical circuits when excessive current is detected. Thermal protection responds to sustained overload conditions, while magnetic protection rapidly disconnects the circuit during a short circuit, helping safeguard wiring, connected equipment and electrical assemblies.
The Lovato P1MB4PB01 uses a B curve characteristic that responds more quickly to overcurrent than C or D curve breakers. This makes it particularly suitable for circuits supplying resistive loads, control equipment, electronic devices and lighting systems where high starting currents are not normally present.
Typical Applications
- Industrial control and automation panels.
- Low-current auxiliary circuits.
- Commercial electrical distribution boards.
- Lighting and resistive load circuits.
- Electronic equipment protection.
- Machine building and OEM equipment.
