The DX1 - 63 LEhigh - breaking - capacity miniature circuit - breaker consists of a plastic shell, an operating mechanism, a contact - arc - extinguishing system, a tripping mechanism, etc. The shell is made of special high - flame - retardant and high - strength plastic, which has strong impact resistance and is lightweight.
The parts of the circuit - breaker's operating mechanism are made of high - strength plastic products. While ensuring sensitivity and reliability, the lowest rotational inertia is achieved, making the time from the start of a short - circuit fault to the tripping - mechanism action very short. The tripping mechanism is composed of two parts: a bimetallic - strip overload - and - delay - tripping mechanism and a short - circuit instantaneous - electromagnetic - tripping mechanism. The contact - arc - extinguishing system adopts special arc - guiding angles and arc - extinguishing chambers, which have significant current - limiting characteristics.
