The TY-Y01 series residual current electrical fire monitoring detector, designed based on the fieldbus communication technology, well integrates measurement, alarm, and address setting functions. It detects the leakage current in a single circuit, triggers an alarm when a fault condition is detected, and reports the alarm information to the monitoring server through the fieldbus. Highly integrated and proper action characteristics, suitable for TN-C-S and TN-S systems at 0.4 kV voltage level.
