Description

TeSys K instantaneous auxiliary contact block, for contactors LC.K, LP.K, CA.K with screw clamp terminals (except LP4K, LP5K, CA4K). It provides 4NC contacts rated up to 10A 690V AC, connection by screw clamp terminals. Front mounting by clip-on, it procures high reliability and durability. Multi standards certified (IEC, UL, CSA, CCC).

Features

The Schneider Electric LA1KN04 auxiliary contact block is engineered for seamless front-mounting integration with your existing TeSys K miniature contactors and control relays, specifically matching the LC1K, LP1K, and CA2K series (excluding LP4K, LP5K, and CA4K). This clip-on, tool-free front mounting system eliminates the need for panel modifications or extensive downtime, allowing you to quickly expand your control circuit footprint without taking up valuable DIN rail real estate.
Featuring a dedicated 4 NC (Normally Closed) contact configuration, this add-on module lets you simultaneously handle four independent interlocking or signaling loops. This layout provides the ideal logic pathways required to implement strict safety drop-outs and operational state feedback within your automated control systems.
To satisfy rigid corporate safety compliance and project acceptance criteria, this module carries comprehensive global listings including UL 60947-5-1, CSA C22.2 No 60947-5-1, CE, UKCA, and IEC 60947-5-1 certifications. It is also an eco-friendly Green Premium product, verifying compliance with RoHS and REACh requirements so you can deploy it safely on any regulated or environmentally conscious work site.
