Auxiliary contact Schneider Electric IACTs A9C15914 — 2A AC/1A DC, white

The Auxiliary Contact Schneider Electric IACTs A9C15914 is a side-mounting contact module that provides one normally open (NO) and one normally closed (NC) contact. It is built for auxiliary switching in control circuits, signaling and interlocking functions and is intended to attach to compatible IACTs devices to expand contactor and motor starter capabilities without altering the main device wiring. The product is supplied in white and includes AC and DC contact ratings suitable for low-power control uses.

Advantages

The module offers compact side mounting to keep the footprint small while preserving the original layout of the primary device. Combining a NO and an NC contact in a single unit enables both control and monitoring tasks simultaneously. Designed by Schneider Electric, the module is intended for reliable mechanical switching within industrial and building automation control circuits.

Suitable for

• Adding an extra signal contact to contactors and motor starters
• Interlocking circuits that require one NO and one NC contact
• Control panel assemblies in industrial automation and building management systems
• Retrofit installations where side-mounted auxiliary contacts simplify fitting

When it may not be suitable

This module is intended specifically for side mounting on compatible IACTs devices and may not fit or function correctly with non-compatible contactors or alternative mounting arrangements. It is a mechanical auxiliary contact module and does not replace electronic monitoring relays or sensors when such electronic functionality is required.

Key specifications

• Contact configuration: 1 normally open (NO) + 1 normally closed (NC)
• AC contact rating: 2 A at 240 V (50/60 Hz)
• DC contact rating: 1 A at 130 V
• Mounting type: side mounting for compatible IACTs devices
• Colour: white
• Intended use: auxiliary switching for control circuits, signaling and interlocking

How to use

Mount the auxiliary contact to the side of a compatible IACTs device following the device manufacturer’s mechanical instructions. With power isolated, wire the NO and NC terminals into the control or signaling circuits according to the electrical schematic for your application. After installation, verify mechanical engagement and electrical continuity, then test the contacts under expected operating conditions before returning the system to normal service.

What to consider before purchase

• Confirm physical and mechanical compatibility with the specific IACTs model in your installation
• Verify that the 1 NO + 1 NC configuration meets your control and signaling requirements
• Ensure the contact ratings (2 A AC, 1 A DC) suit your loads and the protection in the circuit

Usage recommendations

Install and wire the module only with power disconnected and in accordance with local electrical regulations. Use the auxiliary contacts for dry switching of control and signaling circuits and confirm compatibility with safety or interlock schemes before commissioning.
