This DOL starter offers a streamlined solution for motor management by combining contactor and overload relay functionality in one robust housing. Its compact design significantly reduces wiring complexity and saves valuable space within control panels. The unit is built to withstand demanding industrial environments, providing consistent performance and enhanced operational safety for connected machinery. By simplifying the installation process, it helps reduce assembly time and minimizes the risk of wiring errors.

Suitable for

• Small industrial motor control applications
• Automation systems requiring reliable switching
• Integration into electrical control panels
• Conveyor systems and small pump controls

When it may not be suitable

This device is not intended for motors exceeding the 0.25kW power rating or 0.8A current threshold. It is also not suitable for applications requiring soft-start functionality or variable speed control, as it is strictly designed for direct-on-line starting.

Key specifications

• Power rating: 0.25kW
• Rated operational current: 0.8A
• Control voltage: 24V DC
• Type: Direct-on-line (DOL) starter
• Application: Industrial motor control

How to use

The Eaton MSC-D-1-M7 should be mounted onto a standard DIN rail within a protected electrical enclosure. Ensure that the power supply matches the 24V DC control requirement and that the motor leads are connected according to the terminal markings. Before energizing, verify that the overload settings are correctly adjusted to match the motor's full-load current. Once installed, the device can be controlled via the integrated contactor logic to start and stop the motor safely.

What to consider before purchase

• Verify that your motor's power and current ratings align with the 0.25kW and 0.8A specifications.
• Ensure a 24V DC power supply is available for the control circuit.
• Check the physical dimensions to ensure compatibility with your existing control panel layout.

Usage recommendations

Always ensure that the electrical installation is performed by qualified personnel in accordance with local safety regulations and that the device is protected against short circuits using appropriate upstream fuses or circuit breakers.
