R-K Electronics, Inc. Protection Relays & Systems TVM-600-20-0002

The TVM-600-20 is a three-phase voltage relay for motor protection, ensuring operation only when all phases are present, voltages are within range, and phase rotation is correct. It mounts as a plug-in device with an 8-pin octal termination and includes a dust cover. The device operates on 520 to 600VAC, 50/60Hz, with over/under voltage thresholds set at ±16% of nominal voltage. Output contacts are rated for 10A at 250VAC, 1/2 HP at 250VAC, 1/3 HP at 125VAC, and 10A at 30VDC. Pick-up and drop-out delays are fixed at 0.5 seconds. It operates from 0°C to 40°C and is stored from -40°C to 85°C. Weight is approximately 4.5 oz. A status LED indicates normal operation. The unit uses the OT-08 socket for 300, 400, and 600 series variants.
