When it may not be suitable

This device is specifically designed for 24V AC control voltage applications. It is not suitable for systems requiring different coil voltages without an external transformer or converter. Additionally, it should not be used in environments exceeding its specified current or power ratings.

Key specifications

• Rated current: 32A
• Number of poles: 3
• Power rating: 15kW
• Control coil voltage: 24V AC
• Auxiliary contacts: 1 normally open (NO) and 1 normally closed (NC)

How to use

Installation should be performed by a qualified electrician in accordance with local electrical codes. The contactor is typically mounted on a standard DIN rail or via screw mounting within an electrical enclosure. Connect the main power lines to the primary terminals and the control circuit wires to the coil terminals. Ensure all connections are tightened to the specified torque to prevent overheating. Verify that the auxiliary contacts are correctly wired to your control logic before energizing the system.

What to consider before purchase

• Verify that your control circuit voltage matches the 24V AC coil requirement.
• Ensure the 32A current rating is sufficient for your specific motor or load.
• Check the available space in your electrical cabinet for mounting.
• Confirm that the auxiliary contact configuration meets your control circuit needs.

Usage recommendations

Regularly inspect the terminal connections for tightness and check for any signs of debris or dust accumulation within the enclosure to maintain optimal performance and safety.
