Engagement pieces required for electric handle improvement
The motorized closure allows the circuit breaker body to be moved unattended by remote operation or from a distance without requiring significant remodeling and economical and without increasing the size of the circuit breaker. Can be improved to a switchboard. In addition, since the motorized breaker body has no variation in the moving speed of the circuit breaker and can be moved at a constant low speed, the shock acting on both contact portions when connected to the main circuit is also extremely small. To improve durability and reduce the size of special locks.
Without using a locking mechanism, the breaker body
Stops securely at the disconnection position and locks the stop position
To ensure stable connection with the main circuit
Achieve the cormorant effect has to be able to.
