HR5 series fuse type isolating switchDetailed product description：

Scope of application
HR5 series fuse type isolating switch (hereinafter referred to as the switch). It is mainly used in distribution circuits and motor circuits with high short-circuit current, rated voltage AC 600V (45-62Hz), and agreed to heat up to 630A. It is used as a power switch, isolation switch, emergency switch, and circuit protection, but generally not for directly opening and closing a single motor. The performance of this product complies with IEC947-3 and GB14048.3 standards.
