## Long description

The LSiS MMS-FX 2a is a front-mounted auxiliary contact block specifically engineered to enhance the operational capabilities of motor protection circuit breakers. This compact device provides two normally open (NO) contacts, allowing for seamless integration into industrial control circuits and automation systems. By providing reliable status feedback, it ensures that operators can monitor the state of their circuit protection equipment effectively within power distribution networks.
Advantages
This auxiliary contact block offers a robust design that ensures consistent electrical connectivity and long-term reliability in demanding industrial environments. Its front-mounting configuration allows for quick and space-efficient installation directly onto compatible motor protection circuit breakers without requiring additional side clearance. The inclusion of two normally open contacts provides the necessary flexibility for complex control logic and signaling requirements, making it an essential component for modern electrical infrastructure.
Suitable for
Industrial motor control centers
Automation and process control systems
Power distribution panels
Status monitoring of circuit protection devices
This product may not be suitable for applications requiring normally closed (NC) contacts, as this specific model is configured exclusively with two normally open (NO) contacts. It is also not intended for use with circuit breakers outside of the compatible LSiS series, and users should verify mechanical compatibility before installation.
Key specifications
Contact configuration: 2 Normally Open (NO)
Mounting type: Front-mounted
Compatibility: LSiS motor protection circuit breakers
Application: Status signaling and control integration
Installation of the LSiS MMS-FX 2a involves snapping the block onto the front interface of the corresponding motor protection circuit breaker. Ensure that the main power supply is disconnected before attempting to attach or wire the auxiliary block. Once securely attached, the terminals can be wired into the control circuit to provide the desired status signaling based on the position of the main breaker contacts.
What to consider before purchase
Verify the compatibility of your specific motor protection circuit breaker model
Confirm that your control system requires normally open (NO) contact logic
Ensure there is sufficient space for front-mounted accessories in your enclosure
For optimal performance and safety, always ensure that the terminal connections are tightened to the manufacturer's specified torque settings and that the wiring is routed to avoid interference with other components. Regularly inspect the contact block during routine maintenance to ensure continued reliable operation.
