Main circuit rated current 630A current detector

Electrical fire monitoring system residual current detector.
Built-in processor can receive the signal from transformer and handle those signal into two forms as normality and alarming, both of which will be transmitted to the electrical fire monitoring equipment.
The microprocessor will transmit the mode status of normality or alarming to monitoring devices.
