Through-line aperture 50.5mm Residual Current detector

Two-line loop of electrical fire monitoring equipment, non-polarized.
TC-DH01B-50 with specification as below:
Through-line aperture 50.5mm
main circuit rated working current: less than 250A
Dimensions: 150mm × 102mm × 45mm



It has three led indicators works as below:
Running indicator: Green. It flashes when the communication of detector and control panel is working normally.
Leakage alarm: Red. It goes out when the leakage tube is normal. It lights steadily when the leakage tube alarms.
Leakage fault: Yellow. It goes out when the leakage tube is normal. It flashes when the leakage tube sensor is in trouble.

Parameter setup:
The encoding mode of this detector is electrical program which is convenient and efficient.
Connect TCBM5023 electrical programmer with loop terminals of detector(non-polarized).Then the detector can read address and be programmed with addressable code.
Please refer to Hand Held Programmer Installationand Operation Manual for details.
