• Machine tools such as lathes or milling machines
• Material handling equipment
• Pumping systems requiring reverse flow capabilities

When it may not be suitable

This reversing starter is designed for specific electrical parameters and may not be suitable for applications exceeding its 7.5kW power rating or 17A current limit. It is intended for use with 230V AC control circuits and cannot be used in systems requiring different control voltages without appropriate external transformers or modifications.

Key specifications

• Power rating: 7.5kW
• Rated operational current: 17A
• Control coil voltage: 230V AC
• Function: Forward and reverse motor control
• Configuration: Pre-assembled reversing starter

How to use

Installation should be performed by a qualified electrician in accordance with local safety regulations. The unit is designed for DIN-rail or screw mounting within an enclosure. Connect the three-phase power supply to the input terminals and the motor leads to the output terminals, ensuring that the phase sequence is correctly configured for the desired rotation. The 230V AC control circuit must be connected to the designated coil terminals to enable remote switching. Always verify all connections for tightness and ensure the device is protected by appropriate circuit breakers or fuses before energizing the system.

What to consider before purchase

• Verify that your motor power requirements do not exceed 7.5kW.
• Ensure your control system provides a 230V AC signal.
• Check the available space in your control panel for mounting.
• Confirm that the environmental conditions meet the manufacturer's specifications for industrial equipment.

Usage recommendations

Regularly inspect the terminal connections for tightness and check for any signs of overheating or debris accumulation within the control panel to ensure optimal performance and safety.
