Auxiliary contacts for LS Electric motor starters of the MMS series

The MMS-LX 1A1B auxiliary contacts extend the functionality of the LS Electric MMS series motor starters, allowing the addition of auxiliary contacts to the control circuits. These are key components for building reliable and precisely functioning automation systems. They are mounted sideways to the starter, allowing for flexible adaptation to specific installation needs.

Functionality and application

These contacts, equipped with a 1NO (normally open) and 1NC (normally closed) configuration, allow for the implementation of various signaling and control functions. They can be used for:

• Starter status signaling (on/off).
• Controlling other circuit elements, e.g., indirect starters, alarm signaling.
• Building safety circuits.
• Integration with PLC control systems.

Side mounting provides convenience and speed of installation, especially in applications requiring modification of existing installations or adding new functions without the need to replace the entire starter.

Advantages and benefits

• Versatility: Compatibility with LS Electric MMS series motor starters ensures a wide range of applications in various industries.
• Reliability: High quality of workmanship guarantees long-lasting and trouble-free operation in demanding environmental conditions.
• Flexibility: 1NO/1NC contact configuration allows adaptation to specific application needs.
• Simple installation: Side mounting facilitates and speeds up installation and servicing.
• Functionality extension: They allow adding additional functions without the need to replace the entire motor starter, which translates into cost and time savings.

Additionally, using dedicated auxiliary contacts ensures full compatibility with LS Electric starters, which is important for maintaining the warranty and ensuring the correct operation of the system.
