Circuit breaker accessory Schneider Electric A9A15310 — auxiliary contact block A9A15310

Schneider Electric A9A15310 auxiliary contact block is an accessory designed to extend the control and signaling capabilities of compatible Schneider circuit breakers. It provides additional auxiliary contacts that enable remote status indication, integration into control circuits, and interlock functions without altering the primary switching mechanism. The compact design allows straightforward mounting on compatible breaker frames used in both industrial and residential installations where auxiliary contacts are needed for automation or monitoring.

Advantages

The auxiliary contact block delivers clear separation between the main power contacts and auxiliary circuits, ensuring that signaling and control lines operate independently of the load path. It supports reliable status feedback for control systems and can be used to implement electrical interlocks or remote trip/indicator functions. The device is engineered for compatibility with specific Schneider breaker models and offers a compact footprint that minimizes panel space requirements.

Suitable for

• Adding remote status indication to circuit breakers in switchboards and control panels
• Integrating into control logic for automation systems and safety interlocks
• Providing auxiliary contacts for monitoring systems and alarm circuits
• Upgrading existing installations where additional signaling contacts are required

Key specifications

• Function: auxiliary contact block for signaling and control
• Contact type: auxiliary contacts (normally used for NO/NC signaling)
• Mounting: designed for direct attachment to compatible circuit breaker models
• Application environment: suitable for industrial and residential switchgear
• Physical form factor: compact accessory sized to fit standard breaker frames

How to use

Mount the auxiliary contact block onto the compatible Schneider circuit breaker according to the breaker manufacturer’s instructions and ensure mechanical engagement and electrical connections are secure. Connect the auxiliary contacts to the control or signaling wiring, observing correct polarity and wiring diagrams for NO/NC configurations as required by the control system. Verify correct operation by actuating the breaker and confirming the auxiliary contact changes state to provide the expected signal to monitoring or control equipment.

Usage recommendations

Confirm compatibility with the target circuit breaker model before installation and follow applicable electrical safety procedures. Use the auxiliary contacts only within the rated voltages and currents of the control circuit, and perform functional tests after installation to ensure reliable signaling integration.
