Why Choose the Lovato P1MB3PB01 Miniature Circuit Breaker?
The Lovato P1MB3PB01 is a compact and dependable 3-pole miniature circuit breaker (MCB) designed to protect three-phase electrical circuits against overloads and short circuits. As part of the professional Lovato P1MB circuit protection series, it is suitable for industrial control panels, commercial distribution boards, machine building and OEM electrical equipment.
This miniature circuit breaker uses a thermal-magnetic tripping mechanism to automatically disconnect the protected circuit when excessive current or a short circuit occurs. Its B tripping characteristic provides sensitive protection for circuits with low inrush currents, making it suitable for resistive loads, control circuits, lighting systems and general electrical distribution applications.
With a rated current of 1 A, a 10 kA short-circuit breaking capacity and a compact 3-module DIN rail format, the P1MB3PB01 provides simultaneous protection across three conductors. Its 400 V AC rated voltage, robust construction and conformity with recognised international standards support reliable operation in professional electrical installations.
