LS AU-2M 2a Front Auxiliary Contact Block 2NO

The LS AU-2M 2a is a front-mounted auxiliary contact block engineered for seamless integration with compatible LS contactors. This component provides two normally open (NO) contacts, which are essential for managing control and monitoring signals within complex electrical systems. Designed for durability and precision, this accessory allows for the efficient expansion of switching capabilities in various industrial and commercial automation environments.

Advantages

The primary benefit of the LS AU-2M 2a is its compact front-mounting design, which saves valuable space within electrical enclosures while ensuring easy installation. By providing two additional normally open contacts, it enables more sophisticated control logic and feedback loops without the need for larger, more complex relay systems. Its robust construction ensures reliable performance and consistent signal transmission, even in demanding operational conditions, making it a dependable choice for professional electrical installations.

Suitable for

• Industrial automation control panels
• Commercial building management systems
• Motor starter circuits
• Signal monitoring and feedback applications
• Electrical interlocking systems

When it may not be suitable

This auxiliary contact block is specifically designed for use with compatible LS contactors and may not be physically or electrically compatible with contactors from other manufacturers. It is also not intended for high-power load switching, as it is strictly designed for control and signal circuits.

Key specifications

• Contact configuration: 2 Normally Open (2NO)
• Mounting type: Front-mounted
• Compatibility: LS contactors
• Function: Auxiliary signal switching

How to use

To install the LS AU-2M 2a, ensure that the main power supply to the contactor is disconnected to prevent accidental activation. Align the contact block with the designated front mounting interface on the compatible LS contactor. Press the unit firmly until it clicks securely into place. Once installed, connect the control wires to the terminal points according to your circuit diagram. Verify all connections are tight before restoring power to the system.

What to consider before purchase

• Verify compatibility with your specific LS contactor model
• Ensure the 2NO configuration meets your control circuit requirements
• Check available space on the front of the contactor for mounting

Usage recommendations

Always perform a functional test of the control circuit after installation to ensure the auxiliary contacts operate correctly in response to the main contactor state.
