Schneider Electric iSD Signaling Contact 1 CO A9A26907

The Schneider Electric iSD signaling contact is a precision-engineered modular auxiliary device designed to provide reliable remote status indication for circuit breakers and residual current devices. By integrating this component into your electrical distribution panel, you gain the ability to monitor the operational state of your protective devices in real-time, ensuring enhanced visibility and control over your electrical infrastructure.

Advantages

This signaling contact offers seamless integration with compatible modular devices, ensuring a compact and efficient installation within standard electrical enclosures. The 1 CO changeover contact configuration provides versatile feedback options, allowing for both normally open and normally closed signaling logic depending on your specific automation or monitoring requirements. Its robust construction ensures long-term reliability and consistent performance in both industrial and residential electrical systems.

Suitable for

• Remote monitoring of circuit breaker status
• Indication of residual current device operation
• Integration into building management and automation systems
• Electrical distribution panels in residential and commercial buildings

When it may not be suitable

This device is specifically designed for use with compatible Schneider Electric modular protective equipment. It is not intended for use as a standalone power switching device or for controlling high-load electrical circuits directly.

Key specifications

• Contact configuration: 1 CO (changeover)
• Function: Remote signaling of device status
• Compatibility: Designed for modular circuit breakers and residual current devices
• Mounting: DIN rail mountable

How to use

The iSD signaling contact is installed by clipping it onto the DIN rail adjacent to the protective device it is intended to monitor. Ensure that the power supply to the main circuit is disconnected before beginning the installation. Once mechanically coupled with the circuit breaker or residual current device, connect the signaling wires to the terminal blocks according to your monitoring system requirements. Always verify the mechanical linkage and electrical continuity before restoring power to the system.

What to consider before purchase

• Verify compatibility with your specific circuit breaker or RCD model
• Ensure sufficient space is available on the DIN rail within your distribution board
• Confirm that the signaling voltage and current requirements match your monitoring equipment

Usage recommendations

Always consult the technical documentation provided with your specific circuit breaker model to ensure correct mechanical and electrical integration of the auxiliary contact. Regular testing of the signaling circuit is recommended to maintain system reliability.
