LS AU-2M 1a1b Front Auxiliary Contact Block 1NO+1NC

The LS AU-2M 1a1b is a front-mounted auxiliary contact block engineered for seamless integration with compatible LS electrical switchgear. This compact module is designed to provide essential status signaling and control feedback within industrial and commercial electrical systems. By offering a reliable 1NO (normally open) and 1NC (normally closed) configuration, it ensures precise switching performance and enhances the monitoring capabilities of your electrical circuits.

Advantages

The primary benefit of this auxiliary contact block is its straightforward front-mounting design, which allows for quick and efficient installation without the need for complex modifications to existing switchgear setups. Its robust construction ensures consistent operational reliability, providing accurate feedback for automation and control systems. The combination of one normally open and one normally closed contact offers versatility in circuit design, enabling users to implement various interlocking or signaling logic configurations with ease.

Suitable for

• Industrial automation control panels
• Commercial electrical distribution systems
• Motor starter circuits
• Status monitoring and feedback signaling

When it may not be suitable

This auxiliary contact block is specifically designed for use with compatible LS switchgear series. It is not suitable for use with electrical equipment from other manufacturers or incompatible product lines, as the mounting interface and electrical specifications may not align.

Key specifications

• Configuration: 1NO (Normally Open) + 1NC (Normally Closed)
• Mounting type: Front-mounted
• Compatibility: LS electrical switchgear
• Function: Auxiliary status signaling

How to use

To install the LS AU-2M 1a1b, ensure that the main power supply to the switchgear is disconnected to prevent accidental contact. Align the auxiliary contact block with the designated front mounting interface on the compatible LS switchgear unit. Press the module firmly into place until the locking mechanism engages securely. Once installed, connect the control wiring to the corresponding terminals according to your circuit diagram. Verify the connection by testing the contact state changes during manual operation of the switchgear before restoring power.

What to consider before purchase

• Verify compatibility with your specific LS switchgear model
• Ensure the contact configuration (1NO+1NC) meets your control logic requirements
• Confirm that the installation space allows for front-mounted accessories

Usage recommendations

Always perform a functional test of the auxiliary contacts after installation and before putting the electrical system into full operation to ensure that the signaling logic matches your system requirements.
