Functions
1. Switches your pump/ motor on and off.
2. Being based on Star-Delta mechanism the starting torque & current is considerably reduced on the motor.
3. Protects the pump from:
Over – Current
Single phasing condition
Phase Reversal
Phase Unbalanced Condition
Short Circuit.
4. Enables Motor to automatically Switch-On if power resumes when kept in Auto-mode.
5. Indication of power supply to the panel.
6. Indicates current drawn by the motor.
7. Indicates voltage supplied to the panel.
Salient Features
1. Power coated MS enclosure for complete corrosion resistance & sturdiness.
2. Rugged MaU Contactor with wide voltage band (250V to 440V).
3. Fitted with MaU type relay for reliable overload protection.
4. Fitted with SDz5 type preventer used for sensing voltage and for protection from Single Phasing, Phase Reversal and Voltage Imbalance Conditions to the motor.
5. All connections are terminated through appropriate crimping Luggs.
6. Fitted with Digital Meter to show the voltage (Incoming Power Supply) and Current (Motor Current) alternatively.
13. Indication lamps for voltage between the phases and Output to Motor.
