Product details

Function and Application

The HR5 series fuse-type isolating switch (hereinafter referred to as the switch) is mainly used in distribution circuits and motor circuits with high short-circuit current, with an rated voltage of AC 415V and 690V (45~62Hz), and a nominal thermal current up to 630A. It is used as a power switch, isolating switch, emergency switch, and for circuit protection, but it is generally not used for directly switching single motors.
