This contactor is not suitable for applications requiring DC switching or for environments where the control voltage differs from the 230V AC specification. It should not be used in circuits exceeding its rated current or power capacity, as this may lead to equipment failure or safety hazards.

Key specifications

• Number of poles: 3
• Rated operational current: 85A
• Power capacity: 45kW
• Control coil voltage: 230V AC
• Auxiliary contacts: 1NO and 1NC

To use the LS MC-85a, ensure the device is mounted securely on a standard DIN rail or panel surface within an appropriate electrical enclosure. Connect the main power lines to the primary terminals and wire the control circuit to the coil terminals, ensuring the voltage matches the 230V AC rating. Verify that all connections are tightened to the specified torque to prevent overheating and ensure optimal electrical contact.

What to consider before purchase

• Verify that your control circuit voltage is compatible with the 230V AC coil.
• Ensure the motor or load power requirements do not exceed the 45kW limit.
• Check available space in your control panel for mounting dimensions.
• Confirm that the auxiliary contact configuration meets your control logic needs.

Regularly inspect the contactor for signs of wear or debris accumulation and ensure all terminal connections remain tight to maintain safe and efficient operation over time.
