Auxiliary contact Schneider Electric LC1K0910P7 — AC contact 230 V, multi-colour

The Schneider Electric auxiliary contact LC1K0910P7 provides an additional AC contact interface rated for 230 V operation. Designed as a compact accessory for compatible contactors, this multi-colour auxiliary contact extends switching and signalling capabilities in industrial and electrical control circuits. It is intended for installation alongside primary switching devices to enable supplementary control feedback and interlocking functions.

Advantages

This auxiliary contact delivers reliable AC switching at 230 V with a compact footprint that conserves panel space. The multi-colour design improves visual identification during installation and maintenance, reducing the chance of wiring errors. Built for compatibility with standard contactors, it allows straightforward extension of control functions without modifying the main device.

Suitable for

• Extending control circuits and signalling in motor starters and contactor panels
• Providing feedback contacts for automation and safety interlocks
• Use in industrial switchboards, control cabinets, and machine control panels
• Retrofit applications where additional auxiliary contacts are required

Key specifications

• Contact type: AC auxiliary contact suitable for integration with contactors
• Rated voltage: 230 V AC
• Colour: multi-colour for visual differentiation
• Form factor: compact accessory designed for mounting on compatible devices
• Function: extends switching and signalling capabilities in control circuits

How to use

Mount the auxiliary contact to the compatible contactor according to the contactor manufacturer's instructions. Connect control wiring to the contact terminals designated for the auxiliary contact, ensuring that the supply does not exceed the specified 230 V AC rating. Verify correct mechanical and electrical engagement after installation and perform functional tests under no-load conditions before commissioning in active circuits.

Recommendations

Use the auxiliary contact only with contactors and control devices that specify compatibility with add-on contacts. Observe local electrical codes and safety procedures, isolate power before wiring, and confirm terminal tightening and correct polarity where applicable. For long-term reliability, schedule periodic inspections and replace the accessory if signs of wear or contact degradation are observed.
