APPlication

SGM3S SERIES: Adjustable-type MCCB is an industrial circuit breaker newly developed by MAXGE according to the international standard. Its rated insulation voltage is 800V suitable for AC 50Hz, and it can be divided into 125A-1250A. It is used in circuits with rated voltage below 690V,rated working current up to 800A for infrequent transformation and infrequent starting of motors. SGM3S has the function of overload alarm with no tripping. When overloaded, it does not trip,but just output an overload signal to ensure power supply. In addition, the product also has the function of overload, short circuit and under-voltage protection to prevent the circuit and power equipment from being damaged. And it is current adjustable for your requirement within its rated current.
