Schneider Electric LC1D50AB7 auxiliary contact

The Schneider Electric LC1D50AB7 auxiliary contact is an add-on contact block designed to extend control and signaling functions of compatible contactors. It provides an additional AC-rated contact for integration into control circuits and status feedback loops. The unit is compact and intended for mounting on corresponding Schneider Electric contactor families to expand the number of auxiliary contacts without altering the primary device.

Advantages

This auxiliary contact offers a standardized mechanical interface for reliable attachment to compatible contactors, ensuring correct alignment and secure connection. With its AC contact rating and compact design, it enables straightforward extension of control circuits while maintaining consistent electrical characteristics. The product's multicolour housing aids identification within control panels and wiring assemblies.

Suitable for

• Expanding auxiliary contacts on contactors in motor control centers
• Adding signaling or interlocking functions in industrial control panels
• Integrating into automation circuits that require additional status feedback

Key specifications

• Contact type: Auxiliary (add-on) contact block suitable for mechanical mounting on compatible contactors
• Rated AC contact: designed for control and signaling applications at AC voltage levels
• Housing: compact, multicolour for visual identification
• Application: intended for use in control circuits, interlocks, and status feedback systems

How to use

Mount the auxiliary contact onto the designated accessory location of a compatible Schneider Electric contactor following the manufacturer's mechanical guidance. Ensure power to the contactor and control circuit is isolated before installation. After securing the contact block, connect the control wiring to the auxiliary contact terminals according to the circuit schematic, observing proper wire sizes and terminal tightening torques. Verify correct operation by cycling the contactor and checking the auxiliary contact response in the control or indicator circuit.

Usage recommendations

Use the auxiliary contact only with compatible Schneider Electric contactors and within its rated AC control circuit conditions. Confirm wiring and mounting clearances in the control panel and perform functional tests after installation to ensure reliable signaling and interlocking performance.
