R-K Electronics, Inc. Protection Relays & Systems TVM-100-20-0002

The TVM-100 is a three-phase voltage relay for motor protection, detecting overvoltage, undervoltage, phase loss, and incorrect phase rotation. It mounts plug-in with an 8-pin octal termination and includes a dust cover. The unit operates on 100 to 130 VAC, 50/60 Hz, with a fixed 0.5-second pick-up and drop-out delay. Its output contacts are rated at 10 A at 250 VAC, 1/2 HP at 250 VAC, 1/3 HP at 125 VAC, or 10 A at 30 VDC. The relay activates when all phases are present, voltages remain within ±13% of nominal (100 Series), and rotation is A-B-C. Power consumption is 1.5 VA. Operating temperature ranges from 0°C to 40°C, and storage temperature ranges from -40°C to 85°C. The device includes a status LED and weighs approximately 4.5 oz.
