Product Benefits
Miniature circuit breakers (MCBs) safeguard electrical systems from overloads and short circuits in homes, offices, and other buildings, as well as in industrial applications. After detecting a malfunction, the micro circuit breaker instantly disconnects the electrical circuit to prevent wire damage and the danger of fire. MCBs are equipped with two tripping mechanisms to ensure the safety of persons and property: a delayed thermal tripping mechanism for overload protection and a magnetic tripping mechanism for short circuit protection.
With both the thermal and magnetic tripping mechanisms installed, the Aswich DC Miniature Circuit Breaker is intended to safeguard DC electrical installations from overloads and short circuits. The circuit breaker automatically shuts off the electrical circuit when a problem is found to protect the wires and reduce the possibility of a fire. When performing electrical maintenance, the circuit breaker can also be manually opened while carrying its full rated load without suffering any harm. The circuit breaker was designed for reversible connection; it may be wired in either direction and operates on bidirectional current. The built-in indicator window makes it easier to quickly determine the circuit breaker's contact position. The buckle's design makes it simple to install on a DIN rail that is the norm.
