Acrel ARB6 Arc Flash Protection Relay
Acrel ARB6 Arc Flash Protection Relay
General
Acrel ARB6 series arc protection device adopts a modular design (including power module, CPU module, arc acquisition module, analog acquisition module, input/output module, communication module, human-machine interface module, etc.), integrating multiple functions such as protection, measurement, monitoring, control, communication, fault recording, event recording, etc., to monitor arc signals, protection current or voltage signals in real time, Implement arc protection function for 0.4kV~35kV medium and low voltage distribution systems. The device software is equipped with specialized protection algorithms, which have strong anti-interference performance, high reliability, flexible protection implementation methods, and can be used in conjunction with the Acrel-2000 power monitoring system, providing guarantees for the safe and reliable operation of the power system.
