Auxiliary contact Schneider Electric LC1K0910V7, 1 NO + 0 NC, for LC1K contactors, AC rating 400 V

The Schneider Electric auxiliary contact LC1K0910V7 adds one normally open contact (1 NO) to compatible LC1K series power contactors. Designed for control and signaling circuits, this module provides a compact way to extend the switching and status feedback capabilities of LC1K contactors. It is intended for installation directly onto Schneider Electric LC1K contactors and is rated for AC operation up to 400 V.

Advantages

The auxiliary contact module is compact and specifically engineered to integrate with LC1K contactors, reducing wiring complexity while maintaining consistent mechanical and electrical interfaces. Its single normally open contact provides clear switching feedback for control logic and indicator circuits. Being a manufacturer-matched accessory ensures compatibility with LC1K mounting and actuation mechanisms, and the 400 V AC rating makes it suitable for typical industrial and building automation environments.

Suitable for

• Adding a feedback contact to LC1K series contactors in motor control panels
• Signaling circuits for status indication (e.g., remote indicators, PLC inputs)
• Interlocking and control logic where a NO auxiliary contact is required
• Retrofit or upgrade of existing LC1K installations needing an additional contact

When it may not be suitable

This auxiliary contact provides only a single normally open contact and therefore is not suitable when multiple auxiliary contacts or a normally closed contact are required. It is designed specifically for LC1K series contactors; it should not be used with contactors from other series or manufacturers unless explicit compatibility is verified.

Key specifications

• Contact configuration: 1 normally open (1 NO)
• Intended mounting: for Schneider Electric LC1K series contactors
• AC contact rating: up to 400 V
• Function: control and signaling circuit switching / status feedback

How to use

Mount the auxiliary contact module directly onto an LC1K series contactor following Schneider Electric's mechanical mounting orientation and locking procedure. Connect the control or indicator wiring to the auxiliary contact terminals as shown in the contactor documentation, respecting polarity and wiring practices for the control system. After installation, perform functional checks to ensure the contact changes state reliably with the main contactor operation and verify continuity with appropriate test equipment before energizing the control circuits.

What to consider before purchase

• Confirm mechanical compatibility with your specific LC1K contactor model
• Ensure a single normally open contact meets your control or signaling requirements
• Verify that the 400 V AC rating is adequate for your circuit voltage
• Plan wiring and space requirements in the control enclosure for the accessory

Usage recommendations

Use the LC1K0910V7 auxiliary contact for straightforward status feedback and simple control logic additions to LC1K contactors. Follow Schneider Electric installation instructions and local electrical standards when wiring and testing; perform routine inspections to confirm secure mounting and reliable contact operation.
