Key Features & Benefits

1. Direct-On-Line (DOL) Starting Mechanism

• Feature: Utilizes the straightforward Direct-On-Line method for motor activation.
• Benefit: Provides instant full torque, robust starting for motors where high inrush current is permissible, and offers a highly reliable and simple control solution.

2. High-Quality Main Contactor

• Feature: Equipped with a heavy-duty, industrial-grade 3-pole contactor with appropriate current ratings.
• Benefit: Ensures reliable power switching to the motor, capable of handling frequent operations and providing a long operational lifespan with minimal maintenance.

3. Adjustable Thermal Overload Relay

• Feature: Integrated with a precision-engineered thermal overload relay (TOR) with an adjustable current setting.
• Benefit: Offers crucial protection against motor overheating caused by sustained overcurrents or phase imbalances, significantly extending the motor's lifespan and preventing costly damage.

4. Integrated Control Circuitry & Terminals

• Feature: Includes clearly labeled terminal blocks for easy connection of external Start/Stop pushbuttons, Emergency Stop, indicator lamps (Run/Trip), and auxiliary contacts.
• Benefit: Simplifies external wiring, reduces installation errors, and provides clear operational status feedback, making integration into existing control systems straightforward.

5. Phase Loss & Phase Imbalance Protection (Optional/Integrated)

• Feature: Advanced models or integrated relays offer automatic detection and tripping upon phase loss or severe phase imbalance.
• Benefit: Protects the motor from single-phasing conditions, which can lead to severe damage and burnout, enhancing overall system reliability and safety.

6. Robust & Compact Design

• Feature: Constructed on a durable, space-saving panel board, suitable for mounting inside control enclosures. Utilizes high-quality, flame-retardant components.
• Benefit: Maximizes available panel space, ensures long-term reliability in harsh industrial environments, and complies with safety standards.

7. Pre-Wired & Factory-Tested

• Feature: All internal components are expertly pre-wired and rigorously tested at the factory before shipment.
• Benefit: Significantly reduces installation time and labor costs on-site, minimizes potential wiring errors, and ensures reliable operation from day one.

8. Flexible Voltage & Current Ratings

• Feature: Available in various configurations to accommodate standard three-phase supply voltages (e.g., 200V, 400V, 480V AC) and motor power ratings (e.g., 0.75kW to 22kW).
• Benefit: Provides a versatile solution adaptable to a wide range of motor sizes and electrical systems, ensuring a perfect fit for your specific application.

9. DIN Rail & Screw Mounting Options

• Feature: Designed for flexible mounting within a control panel, typically with options for DIN rail or direct screw mounting to the backplate.
• Benefit: Offers versatile installation choices, allowing for easy integration and secure placement within various panel layouts.

Technical Specifications (Typical, configurable based on model)

• Supply Voltage: 3-Phase, 50/60Hz (e.g., 200-240V AC, 380-415V AC, 440-480V AC)
• Motor Power Rating: 0.75 kW (1 HP) to 22 kW (30 HP) - Specify exact range per product variant.
• Contactor Rating: Matched to motor power, typically AC-3 duty.
• Overload Relay Range: Adjustable, e.g., 1.6A - 2.5A, 4A - 6.3A, 10A - 16A, etc. (based on motor rating).
• Control Voltage: 24V AC/DC, 110V AC, or 220V AC (configurable).
• Auxiliary Contacts: 1NO + 1NC (for status indication, interlocking).
• Terminals: High-quality screw terminals for power and control wiring.
• Mounting: DIN rail compatible or direct screw mount.
• Operating Temperature: -10°C to +55°C
