Why Choose the Lovato P1MB1PB25 Miniature Circuit Breaker?
The Lovato P1MB1PB25 is a compact and reliable miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. As part of the Lovato P1MB modular circuit protection range, it provides dependable protection for residential, commercial and industrial electrical installations.
This circuit breaker features a 25 A rated current, a Type B tripping characteristic and a high 10 kA short-circuit breaking capacity. Its Type B response makes it particularly suitable for circuits supplying resistive or low-inrush loads, including lighting, heating, socket outlets and general electrical equipment.
With a single-pole configuration and compact one-module DIN rail design, the P1MB1PB25 can be installed easily in distribution boards, switchboards and industrial control panels. Its thermal-magnetic operating mechanism provides automatic disconnection during sustained overload conditions and sudden short-circuit faults.
