## Summary description

Auxiliary contact block Schneider Electric A9XPH157 designed to provide additional switching contacts for modular control devices. Used to extend contact functionality of pushbuttons, pilot lights or control switches, enabling signaling and interlocking in control circuits. Suitable for industrial and building automation applications where extra auxiliary contacts are required.

## Long description

The Schneider Electric A9XPH157 auxiliary contact block adds supplementary switching contacts to modular control devices such as pushbuttons, pilot lights and control switches. Designed for Harmony-style assemblies, it enables expanded signaling and interlocking functions in control circuits used in industrial and building automation. The unit is intended to integrate with compatible modular operator devices to provide additional changeover or auxiliary contacts without altering the primary device.
Advantages
The auxiliary contact block provides a compact and modular way to increase contact capacity while maintaining the original ergonomics of the control device. It supports straightforward mounting on compatible Harmony-style operators, ensuring reliable electrical switching and repeated mechanical operation. The design helps separate control logic contacts from main power contacts, simplifying wiring for signaling and interlock circuits.
Suitable for
Expanding contact functions of pushbuttons and pilot lights in control panels
Implementing signaling and status feedback circuits in automation systems
Creating interlock schemes in machinery and building automation
Retrofits where additional auxiliary contacts are required without replacing the primary operator
Key specifications
Type: Auxiliary contact block for modular control devices
Compatibility: Designed for Harmony-style modular operators
Function: Provides additional switching contacts for signaling and interlocking
Mounting: Snap-on or clip-on attachment to compatible operators (modular mounting)
Application environment: Industrial and building automation control circuits
How to use
Mount the auxiliary contact block onto a compatible Harmony-style operator following the operator manufacturer's instructions. Ensure the control power is isolated before installation. Align the contact block with the operator’s accessory mounting interface and secure it by snapping or clipping into place until a positive retention is felt. Connect the auxiliary contact terminals into the control or signaling circuit using appropriate wire sizes and terminal tightening torques as specified by the operator documentation. Verify correct operation by operating the main device and observing the auxiliary contact response.
Usage recommendations
Use the auxiliary contact block only with compatible Harmony-style operators and ensure electrical ratings match the control circuit requirements. Perform installation and maintenance with power removed and in accordance with applicable electrical safety standards. For reliable long-term operation, avoid exposure to environments beyond the product’s intended industrial or building automation conditions and consult Schneider Electric documentation for torque, wiring and compatibility details.
