4 Pole Miniature Circuit Breakers

A 4 pole miniature circuit breaker (MCB) is a compact electrical switch designed to protect electrical circuits from overloads and short circuits. It consists of 4 poles, each representing a separate electrical phase. These poles are connected to the respective phases of the electrical system.

The 4P MCB is equipped with a thermal-magnetic tripping mechanism. The thermal part responds to sustained overcurrents, such as an overload, while the magnetic part reacts to high-intensity short circuits. When an excessive current is detected, the MCB trips and interrupts the flow of electricity, preventing damage to the circuit and connected devices.

The miniature size of the micro circuit breaker makes it suitable for use in residential, commercial, and industrial applications where space is limited. It is typically installed in distribution boards or consumer units to provide individual circuit protection. The 4 pole configuration allows for simultaneous protection of multiple phases, ensuring balanced protection across the electrical system.

ATO provides 2 amp, 6 amp, 16 amp, 20 amp, 32 amp, 40 amp, 50 amp, 63 amp 4 pole mini circuit breaker with standard rail mounting for different load requirements. The 4 pole miniature circuit breaker offers reliable and efficient protection against electrical faults, contributing to the safety and stability of electrical installations.
