EFI

This product is a fault section circuit breaker designed to interrupt and reclose to provide stable power supply to the distribution line when faults such as overloads, short circuits, or open circuits occur in the distribution line. It uses Epoxy and Vacuum Interrupter for internal and external insulation, making it environmentally friendly. Additionally, the housing contains sensors capable of measuring voltage and current, allowing for remote control and monitoring of the circuit breaker.
