Product information

Description

The LSiS MMS-LX 2a is a side-mounted auxiliary contact block specifically engineered for integration with LSiS motor protection circuit breakers. This module serves as a critical component in industrial automation, providing reliable signal feedback regarding the status of the main circuit breaker. By utilizing two normally open (2NO) contacts, it allows for effective monitoring and control, ensuring that operational data is accurately transmitted to control systems to enhance overall safety and system visibility.

Advantages

The primary advantage of the LSiS MMS-LX 2a is its seamless compatibility with LSiS motor protection circuit breakers, which ensures a straightforward and secure installation process. Its side-mounting design saves valuable space within electrical enclosures while maintaining robust electrical connectivity. The high-quality construction of the contact block ensures long-term reliability and consistent performance in demanding industrial environments, making it an essential addition for systems requiring precise status monitoring and automated control feedback.

Suitable for

When it may not be suitable

This auxiliary contact block is designed exclusively for specific LSiS motor protection circuit breakers and may not be compatible with circuit breakers from other manufacturers or different series. It is not intended for high-power switching applications, as it is strictly a signal-level auxiliary device.

Key specifications

Contact configuration: 2NO (Normally Open)
Mounting type: Side-mounted
Compatibility: LSiS motor protection circuit breakers
Function: Auxiliary signal feedback

How to use

To install the LSiS MMS-LX 2a, ensure that the main power supply to the motor protection circuit breaker is completely disconnected. Align the auxiliary block with the designated side-mounting interface on the circuit breaker housing. Secure the unit firmly according to the mechanical locking mechanism provided. Once physically attached, connect the signal wiring to the terminal points of the contact block. Verify all connections are tight and that the contact block is properly seated before restoring power to the system.

What to consider before purchase

Verify compatibility with your specific LSiS circuit breaker model
Ensure the 2NO contact configuration meets your control system requirements
Check available space on the side of the circuit breaker within your enclosure

Usage recommendations

Always perform installation and maintenance by qualified electrical personnel. Regularly inspect the terminal connections for tightness and ensure the contact block remains free from dust or debris to maintain optimal signal transmission.
