Industrial C263 Phase Monitor Relay Panel Mount

Description:

The Time Mark C263 3-Phase Power Monitor is designed to continuously monitor 480 VAC three-phase power systems for phase loss, phase reversal, and low-voltage conditions to protect motors and industrial equipment from damaging electrical faults. Commonly installed in motor control panels, HVAC systems, pumps, compressors, conveyors, and industrial machinery where dependable three-phase power monitoring is required. Maintenance teams, OEMs, and system integrators use the Time Mark C263 for replacement, repair, and preventive maintenance to improve equipment reliability and minimize unexpected downtime.

Applications:

The Time Mark C263 is a solid-state three-phase monitor that supervises Wye and Delta power systems without requiring a neutral connection and de-energizes its output relay whenever phase loss, phase reversal, or undervoltage conditions are detected. Featuring automatic reset, panel mounting, and screw terminal connections, it is ideal for industrial automation systems, motor control centers, HVAC equipment, compressors, pumps, conveyors, and manufacturing machinery where continuous power monitoring helps prevent motor damage and production interruptions.
