Rail mounted electrical fire instruments

The rail mounted electrical fire instrument is an intelligent power device designed for TT and TN systems below 0.4kV. It has functions such as single and three-phase AC measurement, four quadrant energy measurement, harmonic analysis, switch input, relay output, as well as RS485 communication or GPRS wireless communication. It monitors and manages fire hazard parameters such as residual current and wire temperature in the distribution circuit.

The product adopts advanced microcontroller technology, with high integration, compact size, easy installation, and integrates intelligence, digitization, and networking. It is an ideal choice for building monitoring devices to prevent monitoring and system insulation aging estimation. At the same time, the original RS485 communication was upgraded to GPRS wireless communication, solving the problem of difficult on-site wiring. As an advanced intelligent and digital acquisition component, this intelligent device has been widely used in various control systems, SCADA systems, and energy management systems.
