Aperture of wires 225 × 56mm current 630A detector

Residual Current Electrical Fire Monitoring Detector TC-DH01B-J225
Through-line aperture: 225 × 56mm
main circuit rated operating current: less than 630A
Dimensions: 296mm × 166mm × 45mm
Standard:
GB14287.2-2014 "Electric Fire Monitoring Systems - Part 2: Residual Current Electric Fire Detectors”
The Detector builds up an electrical fire monitoring system with our productions of JB-DH-TC5600 Electrical Fire Monitoring Equipment, TC-DH12A Combined Electrical Fire Monitoring Detector and TC-DH230 Combined Electrical Fire Monitoring Detector. The Detector can realize the function of leakage test, temperature test and output controlling by connecting with JB-DH-TC5600 Electrical Fire Monitoring Equipment through two-line loops. It can also connect with many other kinds of residual current transformers to realize stable and reliable operating.
Electrical fire monitoring system can effectively prevent electrical fires and reduce losses.
