Auxiliary contact Schneider Electric LC1D18P7 — AC contact 230V, compatible with LC1D series

The Schneider Electric LC1D18P7 auxiliary contact is designed to extend the functionality of LC1D series contactors by providing an additional AC switching contact rated for 230 V. The compact, multicolour housing enables quick visual identification when mounted on control panels or inside electrical cabinets. This accessory supports signaling, interlock and feedback functions in automation circuits and motor control applications.

Advantages

This auxiliary contact offers reliable AC switching at 230 V with construction matched to LC1D contactors, ensuring mechanical compatibility and consistent operation. The multicolour housing improves wiring and maintenance efficiency by making the accessory easy to recognize in complex assemblies. Its design is suitable for integration into control panels, motor starters and industrial switching arrangements where additional contacts are needed for control logic or status indication.

Suitable for

• Control panels and distribution boards for signaling and status feedback
• Automation circuits requiring additional interlocks or auxiliary contacts
• Motor starter assemblies where extra contacts are needed for control or safety circuits
• Retrofit or expansion of LC1D series contactor installations

Key specifications

• Contact type: AC auxiliary contact
• Rated voltage: 230 V AC
• Compatibility: for use with LC1D series contactors (mechanical mounting and electrical interfacing)
• Housing: multicolour for identification
• Typical applications: signaling, interlock, feedback in control and automation systems

How to use

Mount the auxiliary contact onto the appropriate slot or mounting point on the LC1D series contactor according to the contactor’s installation instructions. Connect the auxiliary contact wiring to the control circuit using appropriate wire gauge and terminal tightening torque to ensure secure electrical connections. Use the contact for signaling, interlock or feedback functions as part of the control logic; ensure the connected control circuits operate within the rated 230 V AC parameter.

Recommendations

Verify mechanical compatibility with the specific LC1D contactor model before installation, follow local electrical codes, and de-energize circuits during mounting. Use the multicolour housing as a visual aid for maintenance and label wires or terminals to reflect their control functions.
