LS AU-2M 2b Front-Mounted Auxiliary Contact Block, 2-Pole

The LS AU-2M 2b is a precision-engineered front-mounted auxiliary contact block designed to seamlessly integrate with compatible LS electrical switchgear. This 2-pole accessory serves as a critical component in industrial automation and power distribution systems, providing reliable signaling and real-time control feedback. By enabling accurate monitoring of the main contactor's switching status, it significantly enhances the overall operational safety and functional efficiency of your electrical control circuits.

Advantages

This auxiliary contact block offers exceptional reliability and ease of installation due to its front-mounting design, which allows for quick attachment to the main contactor without requiring extensive modifications to the existing setup. Its robust construction ensures consistent performance in demanding industrial environments, providing stable electrical connections that minimize the risk of signal loss. The compact 2-pole configuration is specifically optimized to provide essential feedback loops while maintaining a space-saving footprint within control panels.

Suitable for

• Industrial automation control systems
• Power distribution and management panels
• Monitoring switching status in motor starters
• Feedback signaling for PLC and relay logic circuits

When it may not be suitable

This contact block is specifically designed for use with compatible LS switchgear series and may not be physically or electrically compatible with contactors from other manufacturers. It is not intended for high-power switching applications and should only be used for control and signaling purposes within its rated electrical limits.

Key specifications

• Configuration: 2-pole (2b)
• Mounting type: Front-mounted
• Compatibility: Designed for LS electrical switchgear
• Function: Auxiliary signaling and status monitoring

How to use

To install the LS AU-2M 2b, ensure that the main contactor is completely disconnected from the power supply to prevent accidental activation. Align the auxiliary contact block with the designated front-mounting interface on the contactor housing. Press the unit firmly until it clicks into place, ensuring that the mechanical linkage is properly engaged. Once installed, connect the control wires to the terminal points according to your wiring diagram. Verify the connection by testing the signaling function before restoring power to the main system.

What to consider before purchase

• Verify compatibility with your specific LS contactor model
• Ensure the 2b contact configuration meets your control circuit requirements
• Check available space on the front of the contactor for installation

Usage recommendations

Always perform a functional test of the auxiliary contacts after installation to confirm that the signaling status correctly reflects the position of the main contactor. Regularly inspect the terminal connections for tightness to maintain reliable signal transmission over time.
