① Double line cavity design
The power supply side is separated from the load side, to ensure the absolutely safe of the load side when the circuit breaker pulls out.
② Electric propulsion and pull out function
Press the push button, the circuit breaker will move in at the same time with the slide until the static and dynamic contactor can contact with each other.
Press the pull out button, the circuit breaker will move out with the slide until it reaches a safe distance between static and dynamic contactor to ensure the load without electricity.
③ Hand-shaking device
When the feeder is under the condition of no electricity, the electric propulsion and pull out can not be used, and manually push and pull out can be used. The effect is the same as an electric device.
④ Installation of a circular observation window on the left side
Here you can see the reliability of the contact of the circuit breaker contactors, clearly observe the movement of internal circuit breaker and the contact situation of the dynamic and static contactor.
⑤ Multichannel temperature sensor
There are 6 wireless temperature sensors installed at the feeder plug to monitor the temperature in real time and to avoid high temperature of the plug due to poor contact.
⑥ The circuit breaker connects with the dynamic contactor with
the conductive block, which increases the stability of the body when the static contactor and dynamic contactor contacts.
