The Micro Magic Auto Switch Star Delta is a reliable, high-performance motor starter controller engineered specifically for three-phase borewell, openwell, and domestic water pumps. Designed to eliminate manual operational hassle while protecting critical motor assets, this controller features built-in Single Phase Prevention (SPP), Dry Run Protection, and Low & High Voltage safeguards. It operates efficiently within a 440V rating across a broad pump power range from 3 HP to 30 HP. By automatically initiating and halting pump motor activity alongside fixed on-delay timer logic, it drastically improves operational reliability and prevents costly motor burnouts across agricultural, commercial, and residential water supply applications.

Features

Automatic Start & Stop: Enables seamless automatic motor operation, reducing the need for constant manual intervention.
Single Phase Prevention (SPP): Actively protects three-phase pump motors from catastrophic single-phasing damage.
Multi-Voltage & Dry Run Shield: Integrated safeguards protect against low/high voltage fluctuations and dry running conditions.
Dual Operation Modes: Allows operators to easily switch between Auto and Manual control modes.
Wide Compatibility Range: Reliably controls 3-phase Direct Online (DOL) starter pump setups ranging from 3 HP to 30 HP.

Applications

Agricultural Irrigation: Automated watering systems for farm crops and field water distribution.
Borewell & Openwell Pumps: Safeguarding submerged and surface agricultural pump motors.
Domestic Water Supply: Controlling residential water tank filling without manual intervention.
Commercial Facilities: Managing water transfer pumps in industrial, hotel, and building complexes.

Usage

Mount the Micro Magic Auto Switch securely near your 3-phase water pump starter panel.
Turn off the main electrical supply and connect the 440V 3-phase line wires according to the included circuit diagram.
Integrate the controller terminal leads into your DOL pump starter circuit for Auto Start and Single Phase Prevention.
Select your preferred operational setting using the Auto/Manual toggle switch.
Restore main power; the controller will monitor phase stability and automatically start the motor after the fixed on-delay timer cycle.
In the event of single phasing or dry running, the unit automatically trips the motor to prevent coil burnout.
