When it may not be suitable

This device is not intended for use in high-voltage power grids or applications requiring current ratings exceeding 16A. It is also not suitable for environments where DC control voltage is required, as this specific model is designed exclusively for 24V AC operation.

Key specifications

• Number of poles: 3
• Rated operational current: 16A
• Control coil voltage: 24V AC
• Auxiliary contact configuration: 1 Normally Open (NO)
• Size: S00

How to use

The contactor should be installed by a qualified professional onto a standard mounting rail or via screw mounting within an electrical enclosure. Ensure that the control circuit is connected to the 24V AC terminals and the main power lines are secured to the appropriate power terminals. Verify that the auxiliary contact is correctly wired to your control or monitoring system before energizing the device.

What to consider before purchase

• Verify that your control circuit voltage matches the 24V AC specification.
• Ensure the 16A current rating is sufficient for your specific load requirements.
• Check the available space in your control cabinet to accommodate the S00 size.
• Confirm that the 1NO auxiliary contact meets your signaling or interlocking needs.

Usage recommendations: Always ensure that the power supply is disconnected before performing any installation or maintenance work. Regularly inspect terminal connections for tightness to prevent overheating and ensure optimal electrical conductivity throughout the device's service life.
