Key specifications

• Number of poles: 4
• Rated operational current: 40A (AC-1)
• Control circuit voltage: 110V AC
• Mounting type: DIN rail or panel mount

How to use

Installation should be performed by a qualified professional in accordance with local electrical regulations. The contactor is typically mounted onto a standard DIN rail within an electrical enclosure. Ensure that the power supply is disconnected before wiring the control coil and the main power terminals. Once securely mounted, connect the 110V AC control signal to the coil terminals and wire the load to the main power poles, ensuring all connections are tightened to the manufacturer's specified torque settings.

What to consider before purchase

• Verify that your control circuit provides a stable 110V AC supply.
• Ensure the 40A AC-1 rating is sufficient for your specific load requirements.
• Check the available space in your electrical cabinet for mounting.
• Confirm the compatibility of the terminal connections with your existing wiring.

Usage recommendations

Regularly inspect the contactor for signs of wear or loose connections during routine maintenance. Ensure the environment remains free of excessive dust, moisture, or extreme temperatures to maintain optimal performance and safety.
