SPPT- Autoswitch

The EAPL SPP-T Auto Switch is an advanced single-phase preventer with built-in auto-restart functionality, designed to protect three-phase motors from phase-related faults such as phase failure, phase reversal, and voltage unbalance. It automatically disconnects the motor during abnormal conditions and restores operation once the supply returns to normal, eliminating the need for manual intervention. This smart and compact unit ensures uninterrupted performance and enhanced motor protection in industrial and commercial applications.

Key Features:

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

• Automatically cuts off power during phase loss or incorrect sequence and auto-restores supply when conditions normalize.

• Prevents motor reverse rotation and single-phasing to avoid mechanical and electrical damage.

• Auto-restart feature eliminates manual resetting after power restoration.

• LED indicators provide clear visual status for power, normal, and fault conditions.

• Compact, panel- or DIN-rail-mountable design for easy installation in control panels.

• Factory-calibrated for accurate, reliable detection and long-term stability.

• Wide operating range: 415 V AC ± 10%, 3-phase, 50 Hz.

• Output relay suitable for direct operation of motor contactors or alarms.

Applications:

• Automatic motor control in pumping systems, compressors, blowers, and fans.

• Motor control centers (MCCs) and starter panels for three-phase equipment.

• Water supply systems, HVAC units, and industrial automation panels requiring automatic protection and restart.

• Environments where unattended operation and fault auto recovery are essential.
