Littelfuse, Inc. Monitor - Relay Output TVM208A100.5S3S

The TVM208A100.5S3S is a three-phase voltage monitoring relay designed to protect motors and sensitive loads from under-voltage, over-voltage, voltage unbalance, phase loss, and phase reversal. It features a microcontroller-based circuit with automatic reset, trip and restart delays to prevent nuisance tripping and short cycling. The device mounts with a single #8 (M5 x 0.8) screw and measures 50.8 mm square by 31.75 mm deep. It operates on 208VAC with a 10% undervoltage trip point, 0.5-second trip delay, and 3-second restart delay. Output is an isolated SPDT relay rated for 10A resistive at 125VAC and 1/4 hp at 125VAC. The relay meets ASME A17.1 Rule 210.6, NEMA MG1 14:30, 14:35, and IEEE C62.41-1991 Level B standards. It includes LED indicators for status and fault conditions. Termination is via 0.25 in. (6.35 mm) male quick-connect terminals.
