It is also not suitable for environments where the auxiliary contact configuration of 0 normally open and 1 normally closed does not meet the specific logic requirements of the control circuit.

Key specifications

• Rated operational current: 9A
• Number of poles: 3
• Control coil voltage: 24V DC
• Auxiliary contacts: 0 normally open, 1 normally closed

How to use

Installation should be performed by a qualified professional in accordance with local electrical regulations. Mount the contactor onto a standard DIN rail or mounting plate within a suitable enclosure. Connect the main power lines to the primary terminals and wire the 24V DC control signal to the coil terminals. Ensure all connections are tightened to the manufacturer's specified torque settings before applying power to the system.

What to consider before purchase

• Verify that the 24V DC control voltage matches your existing control system.
• Ensure the 9A current rating is sufficient for the connected load.
• Check that the auxiliary contact configuration meets your feedback or interlocking requirements.
• Confirm the physical dimensions fit within your existing control cabinet space.

Usage recommendations

Regularly inspect the terminal connections for tightness and ensure the contactor is kept free from dust and moisture to maintain optimal performance over its service life.
