Structural Features
The isolating switch is composed of base, bar type isolator, conducting strip, and fuse hook.
The conducting strip is mounted with fuse hook. After switchingin, it will self-lock, and not automati-cally switch out under the deadweight or electric actuaing force. The isolating force. The isolating switch is designed to be single-pole structure and can stiwchin/out by using hook bar and separately control each phase of 3-phase circuit.
The switches with HRC fusemeet with the following data:
