R-K Electronics, Inc. Protection Relays & Systems TVM-600-22

The TVM series is a three-phase voltage relay designed to protect motors by monitoring line voltage, phase rotation, and phase loss. It is mounted via a plug-in 8-pin octal base with a dust cover and weighs approximately 4.5 ounces. Operating temperature ranges from 0°C to 40°C, with storage from -40°C to 85°C. The 600 series variant operates on 520 to 600VAC, three-phase, with over/undervoltage setpoints of ±16% of nominal voltage. The relay has 10A contacts at 250VAC, 1.5VA power consumption, and a fixed 0.5-second pick-up and drop-out delay. The status LED indicates normal operation. The output rating supports 1/2 HP at 250VAC or 1/3 HP at 125VAC, with a 10A rating at 30VDC. The relay is designed for use with motor starters and is compatible with the OT-08 socket for 300, 400, and 600 series models.
