Three phase auto switch with single phase preventer for three phase motor (3HP to 100HP) (DEV-N)

Three phase auto switch has dry run protection, motor overload protection, single phase preventer, phase sequence detector, power on auto start functionalities for openwell / monoclock / borewell submersible pump. Three phase digital auto switch is designed for three phase openwell / monoblock / borewell submersible pump to operate as per the timer functionalities and provides the motor safety features.

Three phase digital auto switch can operates with 3HP to 100HP pump.

• [FULLY AUTOMATIC OPERATION] Motor will turn ON when power resumes. Power ON auto start function is available.
• [CYCLIC TIMER] Three phase auto switch  has inbuilt cyclic timer to turn ON and OFF the motor as per requirement.
• [MOTOR OVERLOAD PROTECTION] Three phase auto switch  has inbuilt motor overload protection to protect the motor. Users can set the overload setting as per motor rating.
• [DRY RUN PROTECTION] Three phase auto switch  has inbuilt dry run protection to protect the motor. Users can set the dry run setting as per motor rating.
• [DIGITAL DISPLAY] Three phase digital auto switch  has a dual display. It displays voltage, ampere, timer and fault of the motor.
• [COMPATIBLE STARTER PANEL] It can be attached to Borewell / Openwell / Monoblock DOL or Star Delta three phase starter panel.
• [VOLTAGE PROTECTION] It has an inbuilt voltage protection device. Motor will turn off when the supply voltage is not within the range of overvoltage and undervoltage set by the user. It protects the motor from voltage fluctuation.
• [USE OF TRANSFORMER COIL] Three phase digital auto switch has inbuilt heavy quality transformer coil. Transformer coil isolates the main input power to the control unit. This increases the reliability, safety and life cycle of the control unit.
• [SINGLE PHASE PREVENTER] Three phase digital auto switch has inbuilt single phase prevent. It detects the phase loss condition and stops the motor immediately.
• [PHASE SEQUENCE DETECTOR] Three phase digital auto switch detects the sequence of the R,Y,B phase. When the power cables are not connected properly or when phase sequence changes, it protects the motor.
