Electrical Fire Monitoring Detector
This series of DIN-rail/panel-mounted electrical fire monitoring detectors (signal processing units) is a line of high-precision front-end distribution network monitoring equipment, strictly developed and designed in accordance with the national standard GB 14287.2-2014. Featuring a modular design, these products can be directly installed within power distribution cabinets and lighting distribution cabinets on every floor of a building to provide 24-hour, real-time online monitoring of residual currents (leakage) and critical node temperatures within the electrical circuits.
Description
Product Advantages
1. M-BUS Two-Wire Technology · Halving Installation Costs
Utilizing advanced M-BUS two-wire technology, both power supply and data communication share a single pair of wires. The non-polarized connection (requiring no distinction between positive and negative terminals) significantly reduces wiring error rates among field technicians, saving over 50% on cabling and installation costs.
2.Integrated Short-Circuit Protection · Rock-Solid Stability
The unit features powerful, integrated short-circuit protection for its communication lines. Should a short-circuit fault occur at a single front-end node, the unit automatically isolates the fault, ensuring that the normal communication of other monitoring devices on the bus remains completely unaffected.
3.Real-Time LCD Display · Data at a Glance
The device features a built-in high-definition miniature LCD screen. Field electricians can directly view current real-time amperage readings, temperature values, and the device’s current operational status right inside the distribution box, without the need for any external testing instruments.
4.Multi-Layer Password Protection · Preventing Accidental Operation
The system incorporates a multi-level password protection mechanism for operations. Unauthorized personnel are prevented from altering core parameters, effectively eliminating the risk of accidental tampering or unauthorized modification of alarm thresholds by unrelated personnel in the field, thereby ensuring a high level of security.
5.Flexible & Adjustable Alarm Thresholds · Adaptable to Diverse Scenarios
The default alarm threshold of 300mA is fully adjustable. Users can freely configure this setting based on the typical leakage current levels specific to each site, ensuring both high-sensitivity alarming and the complete elimination of false alarms.
6.Compact Design · Rapid Rail or Panel Mounting
The device offers two installation options: standard DIN rail mounting (35mm rail) and panel mounting. Its compact form factor ensures it occupies minimal valuable space within the distribution box, making it a perfect fit for both new project installations and the retrofitting of existing distribution cabinets.
