CM-PFE Phase sequence monitoring relay
The CM-PFE relay is from the CM three-phase monitors range. This relay operates with a rated control supply voltage / three-phase measuring voltage of 208-440 V AC and has a 1 c/o output (closed circuit principle) with contacts rated at 250 V / 4 A. The CM-PFE monitors the phase loss and phase sequence. The corresponding threshold values are fixed. The relay is suitable for monitoring of three phase mains.
