Suitable for

• Motor control and protection circuits
• Industrial automation and control panels
• Switching of resistive and inductive loads
• HVAC system control
• Lighting control systems

When it may not be suitable

This contactor is not intended for applications requiring higher current ratings exceeding 18A or for systems utilizing AC control voltages, as the coil is specifically designed for 24V DC. It is also not suitable for environments with extreme corrosive gases or excessive vibration unless housed in an appropriate protective enclosure.

Key specifications

• Rated operational current: 18A
• Number of poles: 3
• Control coil voltage: 24V DC
• Auxiliary contact configuration: 1 Normally Open (1NO)
• Mounting type: DIN rail or screw mounting

How to use

Installation should be performed by a qualified professional in accordance with local electrical regulations. The contactor is typically mounted on a standard DIN rail within an electrical enclosure. Connect the main power lines to the primary terminals and the 24V DC control signal to the coil terminals. Ensure that all connections are tightened to the manufacturer's specified torque to prevent overheating. The auxiliary contact can be wired into the control circuit for feedback or interlocking purposes.

What to consider before purchase

• Verify that the 24V DC control voltage matches your existing control system.
• Ensure the 18A current rating is sufficient for the connected load.
• Check the available space in your control cabinet for mounting.
• Confirm that the 1NO auxiliary contact meets your logic requirements.

Usage recommendations

Regularly inspect the terminal connections for tightness and ensure the contactor remains free of dust and moisture to maintain optimal performance and longevity.
