Why Choose the Lovato P1MB1MC20 Miniature Circuit Breaker?
The Lovato P1MB1MC20 is a compact and reliable miniature circuit breaker (MCB) designed to protect low-voltage electrical circuits against overloads and short circuits. As part of the Lovato Electric P1MB series, it combines effective circuit protection with a space-saving design suitable for modular distribution boards and industrial control panels.
Featuring a 20 A rated current, Type C tripping characteristic and 6 kA short-circuit breaking capacity, the P1MB1MC20 is suitable for circuits supplying equipment with moderate starting currents. Its thermal-magnetic operating mechanism provides dependable automatic disconnection during sustained overloads and high-current short-circuit faults.
The breaker uses a compact 1P+N configuration, providing overcurrent protection on the phase conductor while simultaneously switching the neutral conductor. Occupying only one DIN module, it helps maximise available space inside consumer units, distribution boards and machine control enclosures.

Reliable Protection for Low-Voltage Circuits
The Lovato P1MB1MC20 uses thermal and magnetic tripping elements to protect electrical wiring and connected equipment. The thermal element responds to prolonged overload conditions, while the magnetic mechanism provides rapid disconnection when a short-circuit current is detected.
Its Type C characteristic makes the breaker suitable for general-purpose circuits and loads with moderate inrush currents, including small motors, transformers, lighting equipment and control devices. The phase-and-neutral switching arrangement also provides effective circuit isolation during maintenance or fault conditions.
Typical Applications
- Residential consumer units and distribution boards.
- Commercial electrical installations.
- Industrial control panels and machinery.
- Socket outlet and general-purpose circuits.
- Lighting and building-services systems.
- Small motors and inductive loads.
- Control transformers and power supplies.
- Heating, ventilation and air-conditioning equipment.
