AC/DC Moulded Case Circuit Breaker

The AC/DC Moulded Case Circuit Breaker is an electrical switch with integrated overload protection, short-circuit protection and (in some models) earth leakage protection. It is designed with a molded case, featuring a compact structure, high protection level and long service life. When the current in the circuit exceeds the rated current of the circuit breaker or when a short circuit occurs, the circuit breaker will automatically trip and cut off the circuit, thus preventing the circuit and equipment from being damaged due to overload or short circuit.

Principle of operation

The working principle of AC/DC Moulded Case Circuit Breaker is based on the thermal and electromagnetic effects of current. When the current in the circuit exceeds the rated value of the circuit breaker, the bimetal inside the circuit breaker will be bent by heat, which will trigger the trip mechanism to cut off the circuit. At the same time, the circuit breaker is also equipped with an electromagnetic release device, when there is a short-circuit current in the circuit, the electromagnetic release device will act quickly to cut off the circuit. In addition, some models of circuit breakers are also equipped with leakage protection, when the leakage current is detected, it will also automatically cut off the circuit.

AC/DC Moulded Case Circuit Breaker

Main Features

High Sensitivity and Fast Response: AC/DC Moulded Case Circuit Breaker is able to quickly detect fault currents in the circuit and cut off the circuit in a very short time, thus protecting the safety of the circuit and equipment.

Multiple Protection Functions: The circuit breaker integrates multiple protection functions such as overload protection, short-circuit protection and (in some models) leakage protection, which can meet the protection needs of different circuits.

Compact structure and high protection level: molded case design, compact structure and high protection level, able to withstand harsh environmental conditions, such as moisture, dust, etc..

Easy to install and maintain: Circuit breakers usually adopt plug-and-play design, which is easy to install and dismantle. Meanwhile, its simple internal structure makes it easy to maintain and overhaul.

Scope of Application

AC/DC Moulded Case Circuit Breaker is widely used in places where electrical protection is required, such as homes, offices, factories, hospitals and so on. Especially in places where both AC and DC circuits need to be protected, such as solar power systems, energy storage systems, charging piles, etc., AC/DC Moulded Case Circuit Breaker is more widely used.
