Company	ABB Low Voltage & Systems
Description	CM-PVx - Three Phase Monitors
Bill of material	ABB - 1SVR730794R2300 + CM-PVS.81S Three-phase monitoring relay 2c/o, 0,0,1-30s, L1-L2-L3=3x200-400VAC
Product ID	1SVR730794R2300
Extended Product Type	CM-PVS.81S
Invoice Description	CM-PVS.81S Three-phase monitoring relay 2c/o, 0,0,1-30s, L1-L2-L3=3x200-400VAC
Description	Three-phase monitoring relay
Long Description	The CM-PVS.81S relay is from the CM three-phase monitors range. This relay operates with a rated control supply voltage / three-phase measuring voltage of 200-400 V AC and has a 2 c/o output with contacts rated at 250 V / 4 A. The CM-PVS.81S monitors the phase parameters over/undervoltage and phase failure. The corresponding threshold values are adjustable. Phase sequence monitoring as well as an ON or OFF tripping delay are selectable. The tripping delay is adjustable over a range of instantaneous to 30 s (0, 0.1-30 s). A sealable transparent cover for protection against unauthorized changes is available as accessory. The device offers screw connection technology with double-chamber cage connection terminals.
