TELE Controls Inc. Protection Relays & Systems G2PU690VS20

The G2PU690VS20 is a 3-phase voltage monitoring relay for undervoltage, phase sequence, and phase failure detection, with a switching capacity of 1250VA at 5A/250V AC and 150VA at 5A/30V DC at +55°C. It features two change-over contacts, operates from 208V to 690V AC, and mounts on a DIN rail (TS 35) with a width of 22.5mm. The device has an IP40 housing, operates between -25°C and +70°C, and meets IEC 60664-1 for overvoltage category III and IEC 60947-5-1 for indicators. The adjustable undervoltage threshold ranges from 180V to 690V with a 2% hysteresis and 25% fixed asymmetry, and the tripping delay is adjustable from 0.1s to 10s. It includes LED status indicators for supply, undervoltage, phase sequence, and output state, with a rated surge voltage of 4kV and mechanical life of 20 million operations.
