Description

MUR-02/04/04F Voltage Monitoring Relays can be used in 1P2W or 3P4W systems. It is self-powered and is adjustable for over and under voltage limits and the trip delay timer and reset timer. it also can detects phase fault. MUR-04F also provide fix 15% phase-phase voltage un-balance and phase sequence protections. It is used in air conditioning systems, electronic control and other automated systems.
