隔离开关 — HR17 系列隔离开关 
HR17 series fuse isolating switch requires 800V insulation voltage, 690V rated working voltage, 630A rated working current and 50Hz rated frequency. It can be used as a power switch, an isolating switch, an emergency switch and a circuit protector in the power distribution of heavy short-circuit current and the motor. However, it’s not used as the direct on-off of the single motor generally. It conforms to IEC60947-3 and GB14048.3.
