Residual Current Detector
The JBF6181 series residual current electrical fire monitoring detector have 2 types and 6 models. One type is a circular transformer, applied to residual current detection of cables. The specific model includes: JBF6181-100, JBF6181-315, and JBF6181-630. The other type is a rectangular transformer, applied residual current detection of copper bar. The specific model includes: JBF6181-315C type, JBF6181-630C type, and JBF6181-1000C.
Product Features• The detector is with 1 indicator representing different state with different colors. Green light flashing means normal operating, and red light steady on means alarming.• Low-power operation, power provided by the loop with a maximum transmission distance of 1500 meters.• Real-time transmission of current value, fault signal and other status signals to the electrical fire monitoring equipment.• The residual current transformer is through potting process and can withstand harsh environment.• Easy product tracking management thorough PSN reading.

There are terminals labeled L1, L2 on the detector. These two terminals are connected to the loop of electrical fire monitoring equipment.
Attention: do not connect the line with power.Precautions• The wire should use ZR-RVS-2x1.5mm2. The cable laying must be separated from the strong electrical cable.• When the communication cable is of shielded twisted pair, the shielding must be well grounded.Note: In order to ensure the stability of the system, the loop prohibits the use of solid cable or non-twisted wires.
