DTB300B combined electrical fire monitoring detector

The DTP300B combined electrical fire monitoring detector independently developed and produced by our company is used in conjunction with the DTP300M series of electrical fire monitoring equipment produced by our company to form an electrical fire monitoring system. The products have passed the test of the National Fire Protection Product Monitoring Center and obtained fire protection Product certificate, DTP300B combined electrical fire monitoring detector can monitor the leakage current, cable temperature, and ambient temperature of the electrical circuit in real time. When the leakage current and temperature are abnormal, the electrical fire detector will monitor and send out sound and light alarms in time The signal is transmitted to the electrical fire monitoring equipment, and the potential safety hazards of the power line and cable can be found in time, which can effectively avoid the fire hazard caused by the electrical line failure.
