When it may not be suitable

This device is not intended for applications requiring currents exceeding 6A or for systems operating on DC control voltages. It should not be used in environments that exceed its specified environmental protection ratings or temperature limits.

Key specifications

• Number of poles: 3
• Rated operational current: 6A
• Control coil voltage: 230V AC
• Auxiliary contacts: 1 normally open (1NO)

How to use

The contactor should be mounted on a standard DIN rail or a flat surface within a suitable 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 poles, and the auxiliary contact can be wired into the control logic as needed. Always verify that all connections are tightened to the manufacturer's torque specifications to prevent overheating or loose contact.

What to consider before purchase

• Ensure the 6A current rating is sufficient for your specific load requirements.
• Verify that your control system provides a 230V AC signal.
• Check the available space in your electrical cabinet for mounting.
• Confirm that the auxiliary contact configuration meets your control logic needs.

Usage recommendations

Always perform installation and maintenance by a qualified electrician in accordance with local electrical codes and safety regulations to ensure optimal performance and user safety.
