Stairs starter 1.5kW 400V DOL WEG

The WEG 1.5kW DOL Starter is a high-reliability industrial control unit engineered for the starting and protection of three-phase electric motors. Specifically calibrated for a 400V supply, this Direct-On-Line (DOL) assembly provides a robust, "full-voltage" starting method, delivering immediate torque to the motor for applications such as water pumps, conveyors, and small agricultural machinery.

Technical Engineering and Protection

• Integrated Contacting and Switching: The unit features a high-performance WEG contactor designed for frequent switching cycles. The silver-alloy contacts ensure high electrical conductivity and long-term durability under heavy inductive loads.
• Thermal Overload Protection: The starter is equipped with a precision-calibrated thermal overload relay. This component monitors the motor’s current draw and will automatically trip the circuit in the event of an overcurrent or phase-loss condition, preventing expensive winding burnouts.
• Phase-Failure Sensitivity: Engineered for industrial power grids, the internal relay is sensitive to phase-loss, ensuring the motor is disconnected immediately if one phase drops out, thereby protecting the mechanical integrity of the drive system.
• 400V Three-Phase Calibration: This specific model is wound for standard 400V AC control circuits, making it a "plug-and-play" solution for standard industrial and agricultural power boards.

Structural Integrity and Safety

• IP65 Weatherproof Enclosure: The starter is housed in a high-impact, UV-stabilized polycarbonate enclosure. With an IP65 rating, the unit is completely dust-tight and protected against water jets, making it suitable for installation in wash-down areas, dairies, and outdoor pump stations.
• Ergonomic Operator Interface: The front panel features high-visibility "Start" (Green) and "Stop/Reset" (Red) push-buttons. The Stop button is often designed with a "stay-put" or mushroom-head profile for rapid emergency deactivation.
• Ample Wiring Space: The internal chassis is designed with generous clearance for heavy-gauge industrial cabling. Knockouts are provided at the top and bottom of the enclosure to accommodate standard 20mm or 25mm cable glands.

Operational Application

The 1.5kW (2HP) rating makes this starter the industry standard for small-to-medium-duty motors. Because it is a DOL starter, it applies full line voltage to the motor terminals upon activation, providing the necessary starting torque for high-inertia loads.

Designed for rapid installation and minimal maintenance, the WEG DOL Starter is an essential component for any automated or manual motor control system. Its combination of rugged environmental protection and precision electrical monitoring ensures a long operational lifespan for both the starter and the motor it protects.
