PMD-03

The EAPL PMD-03 is a high-accuracy, three-phase monitoring relay designed to protect motors and electrical systems from phase reversal, phase loss, and voltage unbalance conditions. It continuously supervises the incoming three-phase supply and instantly trips the output when an abnormality is detected, ensuring safe, reliable, and uninterrupted operation of connected equipment. Engineered for durability and ease of use, the PMD-03 is ideal for industrial automation and process-control environments.

Key Features:

• Continuously monitors phase sequence, phase failure, and voltage imbalance in three-phase systems.

• Detects reverse phase rotation and isolates the circuit to prevent motor damage.

• Immediate trip action on phase loss or severe voltage deviation.

• LED indicators clearly show power status and fault condition.

• Compact, DIN-rail or panel-mount design for quick installation in control panels.

• Factory-calibrated for consistent accuracy and performance.

• Wide operating voltage range: 415 V AC, 3-phase, 50 Hz.

• Output relay suitable for driving contactors, alarms, or control interlocks.

Applications:

• Motor protection in pumps, compressors, conveyors, and fans.

• MCCs, control panels, and industrial automation systems.

• HVAC, water-treatment, and process-control equipment requiring phase supervision.

• Any three-phase installation where incorrect sequence or phase loss could cause damage or downtime.
