CM-PFE Phase sequence monitoring relay 1c/o, L1-L2-L3=208-440VAC
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.
Multifunctional Three Phase monitoring relay CM-PVE 320-460VAC
CM-PVE Phase monitoring relay 1n/o, L1,2,3=320-460VAC
The CM-PVE relay is from the CM three-phase monitors range. This relay operates with a rated control supply voltage / three-phase measuring voltage of 320-460 V AC and has a 1 n/o output (closed circuit principle) with contacts rated at 250 V / 4 A. The CM-PVE monitors the phase loss, overvoltage and undervoltage. The corresponding threshold values are fixed. The relay is suitable for monitoring of three phase mains.
