Key specifications

• Number of poles: 3
• Rated operational current: 9A
• Control circuit voltage: 42V AC
• Auxiliary contacts: 1 NO + 1 NC
• Mounting type: DIN rail or panel mount

How to use

Installation should be performed by a qualified electrician in accordance with local safety regulations. The contactor is typically mounted on a standard DIN rail or directly onto a backplate within an electrical enclosure. Connect the power cables to the main terminals and ensure the control wires are securely attached to the coil terminals. Verify that the control voltage matches the 42V AC specification before energizing the circuit to prevent damage to the coil.

What to consider before purchase

• Verify that your control circuit voltage is exactly 42V AC.
• Ensure the 9A current rating is sufficient for your specific motor or load requirements.
• Check available space in your electrical cabinet for mounting.
• Confirm compatibility with existing auxiliary contact requirements.

Usage recommendations

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