SPP-T

The EAPL SPP-T is a compact, high-performance single-phase preventer designed to protect three-phase motors and equipment from damage caused by phase failure, phase reversal, or unbalanced supply conditions. It ensures that the motor operates only when all three phases are healthy and correctly sequenced, automatically disconnecting the circuit during any fault. Built for precision and reliability, the SPP-T is ideal for industrial and commercial motor protection applications.

Key Features:

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

• Prevents motor operation during reverse phase rotation or missing phase conditions.

• Automatically disconnects the circuit under fault conditions and restores power when the supply returns to normal.

• LED indicators provide clear status display for healthy and faulty phase conditions.

• Compact, DIN-rail or panel-mountable design suitable for control panels and MCCs.

• Factory-calibrated for accurate fault sensing and reliable operation.

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

• Output relay for direct control of contactors or alarms.

Applications:

• Three-phase motor protection for pumps, compressors, fans, and conveyors.

• Motor control centers (MCCs) and starter panels.

• HVAC systems, refrigeration units, and process automation panels.

• Industrial machinery requiring continuous phase monitoring and automatic protection.
