Auxiliary contacts: 1NO and 1NC
How to use
The contactor should be mounted on a standard DIN rail or via screw mounting within a protected electrical enclosure. Connect the main power lines to the input and output terminals, ensuring that the wire gauge is appropriate for the 9A load. The 230V AC control signal should be wired to the coil terminals to trigger the switching mechanism. Always verify that all connections are tightened to the manufacturer's specified torque to prevent overheating.
What to consider before purchase
Verify that your control circuit voltage matches the 230V AC coil requirement.
Ensure the motor or load power does not exceed the 4kW limit.
Check available space in your enclosure for mounting.
Confirm if additional auxiliary contacts are required for your specific control logic.
Usage recommendations
Always perform a thorough inspection of the wiring and ensure the power supply is disconnected before installation or maintenance. Regularly check terminal connections for tightness to maintain optimal electrical contact and prevent potential arcing.
