Isolation Switch

SGR2 series fuse combination isolation switch

SGR2 series fuse combination isolation switch switch for short hereinafter). is suitable in the circuit of AC 50Hz, AC rated insulation voltage 800V, rated working voltage 400V,690V, rated working current 160A~630A. It can be used in the circuit of power-distribution or electromotor to isolate the high short-circuit as switch of the power and for isolation. However,It is not to be used to switch-on/off directly the single electromotor.It is without the protective function of overload and short circuit when the fuse combination replaced by the isolating bar (knife), only to isolate the circuit according to the rated making and breaking capacity.
