Robust DOL Motor Starter Control Panel

Overview

The DOL (Direct On-Line) Motor Starter Control Panel is an essential and highly reliable solution for efficiently starting and stopping three-phase induction motors. Engineered for simplicity and robust performance, this pre-assembled and pre-wired panel provides comprehensive motor protection against common electrical faults, ensuring the longevity and safe operation of your machinery. Ideal for applications where motors operate at a constant speed and direct starting current is acceptable, our DOL panels offer a cost-effective and dependable motor control solution.

Key Features

• Direct On-Line (DOL) Starting: Provides a simple and immediate method for starting motors by directly connecting them to the full supply voltage.
• Integrated Motor Protection:
  • Thermal Overload Protection: Equipped with an adjustable thermal overload relay to safeguard the motor from sustained overcurrents caused by mechanical overloads or phase unbalance.
  • Short Circuit Protection: Features a high-rupturing capacity (HRC) fuse or a Miniature Circuit Breaker (MCB) / Moulded Case Circuit Breaker (MCCB) for instant protection against short-circuit faults.
  • Phase Loss/Phase Imbalance Protection (Optional): Advanced models can include relays to protect the motor from damage due to missing or unbalanced phases.
• User-Friendly Interface:
  • Start/Stop Push Buttons: Clearly labeled, robust push buttons for manual motor control.
  • Emergency Stop Button: Latching type emergency stop button for immediate shutdown in critical situations, enhancing operator safety.
  • Run/Trip Indicator Lamps: High-visibility LED indicator lamps for "Motor Run," "Motor Stop," and "Trip" status, allowing for quick operational diagnostics.
• Durable Enclosure:
  • High IP Rating: Available in various IP ratings (e.g., IP54, IP55, IP65) to protect internal components from dust, moisture, and water ingress, suitable for demanding industrial environments.
  • Robust Construction: Manufactured from powder-coated mild steel (MS) or corrosion-resistant stainless steel (SS 304/316) for superior durability and longevity.
• High-Quality Internal Components: Utilizes premium-grade contactors, overload relays, circuit breakers, and terminal blocks from reputable manufacturers, ensuring reliability and extended service life.
• Pre-wired & Factory Tested: Each panel is meticulously wired and thoroughly tested in our factory, reducing installation time and ensuring immediate, reliable operation upon delivery.
• Convenient Cable Entry: Designed with suitable gland plates or knockouts for easy and secure cable termination.
• Modular Design: Facilitates easy maintenance, inspection, and potential upgrades.
