The LAD311 is an auxiliary contact block manufactured by Schneider Electric. Auxiliary contact blocks are used in conjunction with contactors and circuit breakers to provide additional contacts for signaling, interlocking, or other control functions. They are typically mounted directly onto the contactor or circuit breaker, adding extra normally open (NO) or normally closed (NC) contacts to the device.

Applications:

• Contactors
• Circuit breakers
• Motor starters
• Control panels
• Automation systems

Features:

• Adds auxiliary contacts to contactors/breakers
• Various contact configurations available (NO/NC)
• Easy mounting
• Compact size
• Reliable operation

Benefits:

• Expanded control functionality
• Increased system flexibility
• Improved safety

Additional Details:

The Schneider Electric LAD series auxiliary contact blocks are designed for easy integration with their TeSys D contactors and other compatible devices. The LAD311 likely has a specific contact configuration. Based on common Schneider Electric naming conventions, LAD311 is likely a 1NO+1NC auxiliary contact block. Consult the manufacturer's datasheet to verify the specific contact configuration (number of NO and NC contacts), voltage and current ratings, and compatibility with specific contactor models. The datasheet will also provide mounting instructions and wiring diagrams.
