Industrial 2742-115 Three-Phase Current Monitor

Description:

The Time Mark 2742-115 Current Monitor is designed to monitor overcurrent and undercurrent conditions on three-phase electrical systems operating from a 100–130 VAC control power source to help protect motors and industrial equipment. Commonly installed in motor control centers, pump stations, conveyors, compressors, and process automation systems where continuous current monitoring is essential for reliable operation. Maintenance teams, OEMs, and system integrators use the 2742-115 for replacement, repair, retrofit, and preventive maintenance to minimize equipment damage and reduce unplanned downtime.

Applications:

The Time Mark 2742-115 is a solid-state three-phase over/under current monitor that continuously supervises current levels on three-phase lines or three individual single-phase circuits. It is widely used in industrial motor protection, water and wastewater facilities, HVAC systems, conveyor equipment, compressors, and manufacturing machinery where early detection of abnormal current conditions helps prevent equipment failure and production interruptions.
