KEDU CKDM1 molded case circuit breaker MCCB (hereafter referred to circuit breaker), is a new type of circuit breaker researched and developed by the company by using advanced technology. Its rated isolation voltage is 800V, suitable for infrequent switching in lines at AC 50/60Hz, rated voltage of 690V and below, rated current of 16A to 630A. The circuit breaker has the function of overload, short-circuit and under-voltage protection, can protect circuit and power equipment from being damaged.
According to the rated short-circuit breaking limit capacity(Icu), the circuit breaker can be divided into: F low-breaking type, N standard type, H superior breaking type, S high breaking type, L super-high breaking type.
The circuit breaker is characterized with small size, high breaking capacity and short flying arc(zero flying arc for part of specification), vibration resistance, etc.
The circuit breaker can be installed vertically(i.e. vertical installation), and horizontally (i.e. horizontal installation).
