Why Choose the Lovato P1MB1PB63 Miniature Circuit Breaker?
The Lovato P1MB1PB63 is a compact and dependable 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 reliable protection for residential, commercial and industrial electrical installations.
This circuit breaker features a 63 A rated current, a Type B tripping characteristic and a high 10 kA short-circuit breaking capacity. Its Type B response is suited to circuits with relatively low inrush currents, including resistive loads, heating equipment and suitable power distribution applications.
With its single-pole configuration and compact one-module DIN rail design, the P1MB1PB63 can be installed efficiently in distribution boards, switchboards and industrial control panels. Its thermal-magnetic operating principle provides automatic disconnection during prolonged overload conditions and sudden short-circuit faults.

Reliable Circuit Protection for Electrical Installations
Miniature circuit breakers protect electrical cables, equipment and connected loads by automatically disconnecting the power supply whenever excessive current is detected. The Lovato P1MB1PB63 combines thermal protection for sustained overload conditions with magnetic protection for rapid operation during short-circuit faults.
Its 63 A rating makes it suitable for higher-capacity final circuits, distribution circuits and equipment supplies where a Type B response is appropriate. The compact modular design also enables panel builders and electrical contractors to maximise available space within electrical enclosures.
Typical Applications
- Residential and commercial distribution boards.
- Higher-capacity power distribution circuits.
- Industrial switchboards and electrical panels.
- Heating and resistive electrical loads.
- Machinery auxiliary power supplies.
- Building services installations.
- Automation and OEM equipment.
