When it may not be suitable

This contactor is designed for specific electrical parameters and may not be suitable for applications requiring higher current ratings beyond its 16A capacity. It is also not intended for use in environments where the control voltage differs from the 230V AC specification.

Key specifications

• Number of poles: 3
• Rated operational current: 16A
• Control coil voltage: 230V AC
• Auxiliary contact configuration: 1 Normally Open (NO)
• Size: S00

How to use

The contactor should be mounted on a standard DIN rail or via screw mounting within a protected electrical enclosure. Ensure that the power supply matches the 230V AC coil voltage before connecting the control wires to the coil terminals. The main power lines should be connected to the primary terminals, while the auxiliary contact can be integrated into the control circuit for feedback or interlocking purposes. Always verify that all connections are tightened to the manufacturer's specified torque to prevent overheating.

What to consider before purchase

• Verify that the 16A current rating is sufficient for your specific load requirements.
• Ensure your control circuit provides a 230V AC signal.
• Check available space in your control cabinet to accommodate the S00 size.
• Confirm that the 1NO auxiliary contact meets your feedback or signaling needs.

Usage recommendations

Always ensure that the electrical system is de-energized before performing any installation or maintenance work on the contactor. Regularly inspect the terminals for tightness and check for signs of wear or environmental contamination to maintain optimal performance over the device's lifespan.
