Telemecanique RM3TR112VS7 Time Delay Relay Contactor

Description:

The Telemecanique RM3TR112VS7 is a three-phase supply monitoring relay designed to supervise 300–500 V AC power systems with an adjustable time delay and a 5 A output contact for reliable phase protection. Commonly installed in motor control centers, industrial control panels, pumps, compressors, conveyor systems, and process automation equipment where continuous three-phase voltage monitoring is essential. Maintenance teams, OEMs, and system integrators use this monitoring relay for equipment replacement, preventive maintenance, retrofit projects, and maintaining dependable protection against phase failure, phase sequence errors, and voltage imbalance.

Applications:

The Telemecanique RM3TR112VS7 monitors three-phase electrical supplies to detect phase loss, incorrect phase sequence, and adjustable voltage threshold conditions, helping protect motors and industrial equipment from electrical faults. It is widely used in manufacturing plants, water treatment facilities, material handling systems, HVAC installations, and industrial automation applications where reliable three-phase supply monitoring minimizes equipment downtime and improves operational safety.
