HM1 Series MCCB

Product Description

HM1 series MCCB (hereinafter referred to as breaker) is developed by our company with international advanced technology. Its rated insulation voltage is 800V. the breaker is mainly used in distribution network of AC 50Hz /60 Hz, rated voltage up to 690V, rated working current up to 1025A to distribute electric power and to protect the line and the equipment from being damaged due to overload, short circuit and under-voltage protections.
The product features small volume, high switch-off ability and short arcing distance so that it is an ideal product for users.
The breaker is vertically mounted
The product is in conformity with the standards IEC947-2 and GB14048. 2.
All accessories, including shunt release, under-voltage release, auxiliary contact and alarm contact, are made into individual module and can be fitted into breaker conveniently. They have reliable working performance.
