Description
About the Product
The Three Phase DOL Controller for Submersible Pump Application is a control & protection unit designed for starting & operating three phase submersible pump motors.
It enables direct-on-line (DOL) starting by applying full voltage to the motor, making it suitable for borewell systems, irrigation setups, & industrial water pumping applications.
How the DOL Controller Works
This controller ensures efficient motor starting & safe operation by managing electrical control functions:
• Directly connects the motor to the supply for DOL starting
• Provides instant full voltage to initiate motor operation
• Controls switching during start & stop conditions
• Monitors electrical parameters during operation
• Protects the motor from abnormal electrical conditions
DOL controllers are widely used where motors are designed to start under full voltage conditions.
Electrical Configuration
• Phase: Three Phase
• Control Type: Direct-On-Line (DOL) Starter
• Application: Submersible pump motor control
• Function: Motor starting & protection
• System Compatibility: Low-voltage three phase systems
• Usage: Full voltage starting method
Construction & Design
The controller is engineered for durability & consistent field performance:
• Integrated control & protection components
• Strong enclosure suitable for panel-based installations
• Designed for stable & continuous motor operation
• Optimized internal configuration for reliable performance
• Suitable for use in agricultural & industrial environments
Safety & Protection
• Protects motors from overload conditions
• Helps prevent failures due to voltage fluctuations
• Provides phase-related protection for safe operation
• Ensures controlled switching of electrical circuits
• Enhances overall system safety & reliability
Mounting & Durability
• Designed for panel mounting installations
• Suitable for pump control panels & enclosures
• Built to withstand typical outdoor environmental conditions
• Resistant to dust & moisture in agricultural setups
• Ensures long service life with consistent performance
Application Domains
• Submersible pump control systems
• Borewell installations
• Agricultural irrigation systems
• Water pumping applications
• Industrial fluid management systems
Key Features
• Three phase DOL controller for pump applications
• Enables direct-on-line motor starting
• Integrated control & protection functionality
• Suitable for submersible pump systems
• Durable & field-ready construction
• Designed for agricultural & industrial use
• Easy integration into electrical panels
Applications
• Irrigation & farming systems
• Borewell pump installations
• Industrial pumping systems
• Motor control panels
• Water supply systems
FAQs
1. What is a DOL controller used for?

Warranty
- All products listed in the price list are covered by a warranty against manufacturing defects for a period of 18* months from the date of purchase.
- For Lauritz Knudsen MCBs & Isolators mounted inside Lauritz Knudsen Distribution Boards, an extended warranty of 5 years is provided.
- In the event of a defect due to faulty workmanship or other associated reasons, the manufacturer will, at its discretion, remedy the defect or replace the faulty parts or the entire product as soon as possible, free of cost.
- This warranty is subject to proper usage and efficient maintenance and does not cover defects arising from fire, accidents, inefficient maintenance, faulty operation, or deliberate or accidental damage.
- The warranty does not cover damage to power electronic components such as thyristors & IGBTs, which primarily fail due to over-temperature or over-voltage. Users must take adequate precautions to eliminate such conditions.
- The manufacturer shall not be responsible or liable for any special, incidental, social, or consequential losses (including loss of profits), punitive damages, injury, or damages of any kind solely attributable to defect or failure of its products.
- The manufacturer shall not be liable in any manner for issues related to or failure in the performance of any other equipment to which the product is connected.
