Key specifications

• Number of poles: 3
• Rated operational current: 12A
• Control circuit voltage: 42V AC
• Application type: Industrial control
• Design: Compact modular construction

How to use

The device should be installed by a qualified professional onto a standard DIN rail or mounted directly onto a panel. Ensure that the power supply is disconnected before wiring the control and power terminals. Connect the control wires to the coil terminals and the load wires to the main power poles according to the wiring diagram. Verify all connections for tightness and ensure the voltage matches the 42V AC specification before energizing the circuit.

What to consider before purchase

• Verify that your control system provides a 42V AC signal.
• Ensure the 12A current rating is sufficient for your specific load.
• Check available space in your electrical cabinet for mounting.
• Confirm compatibility with existing auxiliary contact blocks if needed.

Usage recommendations

To ensure optimal performance and safety, perform regular inspections of the contactor terminals to ensure they remain tight and free from oxidation. Avoid exposing the device to excessive dust, moisture, or extreme temperatures outside the manufacturer's specified operating range.
