HR6（3/5/17）系列熔断器式隔离开关(以下简称开关)主要用于额定电压交流400V和1000V(45~62Hz)，约定发热电流至  800A的具有高短路电流的配电电路和电动机电路中，作为电源开关、隔离开关、应急开关、并作电路保护用，但一般不作为直接开闭单台电动机之用。

符合标准：GB 14048.3、IEC 60947-3。

The HR6 (3/5/17) series fuse-type disconnecting switch (hereinafter referred to as the "switch") is primarily designed for distribution circuits and motor circuits with high short-circuit currents, operating at rated AC voltages of 400 V and 1000 V (45–62 Hz), with a specified heating current rating up to 800 A; it serves as a power switch, disconnecting switch, emergency switch, and circuit protection device; however, it is generally not intended for directly switching individual motors.

Complies with: GB 14048.3, IEC 60947-3.
