Auto recloser

The product realizes automatic detection and reclosing of circuit breakers.
If there is no fault, it will automatically reclose, and if there is a special fault, it will output a signal to the console.

Automatic reclosing protector ensures continuous power supply

I/O Control
When the CJ51RAi is in Auto mode, connect the device to the power supply, and use the I/O interface to remotely control the device to switch on and off.
1.Adjustable time and frequency.
2.Excessive auto-reclosing equipment will lock the product.
3.Modular assembly, more flexible installation can be adapted to more circuit breakers.
