This Three-Phase Auto Switch is designed to protect and control openwell, monoblock (tullu), and borewell submersible pumps, offering multiple safety and operational features:

Key Features:

1. Motor Protection:

   • Dry Run Protection: Automatically stops the motor if it runs without water, preventing damage.
   • Motor Overload Protection: Safeguards the motor from overload conditions by cutting off power when excessive current is detected.
   • Single Phase Preventer: Detects the loss of one phase and prevents the motor from operating under unsafe conditions.
   • Phase Sequence Detector: Ensures correct phase sequence, preventing motor damage due to incorrect wiring or phase reversal.
   • Undervoltage & Overvoltage Protection: Protects the motor from low and high voltage situations, preventing operational damage.

2. Timer Functionality:

   • Cyclic Timer: Used for continuous switching operations, ideal for applications like Fogger Irrigation, Hydroponics, or Circulation Pumps that require 24/7 operation.
   • Countdown Timer: A combination of a Cyclic Timer and an Auto Cut-Off Countdown Timer that automatically turns off the device after a set time. Commonly used for motors, water pumps, heaters, and geysers.
   • Adjustable Time Range: Set from 1 to 999 seconds/minutes for both ON/OFF functions.

3. Ease of Use:

   • Simple Operation: Easy-to-use timer settings for reliable and consistent motor management.
   • High Quality: Built for long-lasting performance with a robust design.

4. Electrical Specifications:

   • Input/Output Voltage: 230V AC, 15 Ampere/1 HP for efficient power handling.

5. Warranty: Comes with a 1-Year Warranty and is Made in India, ensuring both reliability and support.

This three-phase auto switch is ideal for applications requiring motor protection, precise timing, and safe operation of submersible pumps in water lifting, irrigation, and other similar systems.
