It provides 1 normally open and 3 normally closed instantaneous contacts, wired via spring terminals accepting 0.75 to 1.5 mm² flexible or rigid cable. ## Key Ratings and Compliance Rated conventional free air thermal current (Ith) is 10 A at 50 °C, which governs the continuous current-carrying capacity in the panel — the limiting figure for sizing the control circuit wiring and fuse protection. Rated insulation voltage (Ui) is 690 V per IEC 60947-5-1, with 600 V ratings under UL and CSA standards, confirming suitability for 480 V and 600 V class control panels in North American and IEC markets. Rated making capacity is 110 A at 10 MOhm, meaning the contacts can close onto a short-circuit or inrush condition at that level without welding. IP20 finger protection per IEC 60529 is standard for enclosed panel mounting — no additional touch protection needed inside the cabinet. Front-mounting on TeSys K contactors and reversing starters, the block occupies 38 mm width, 30 mm height, and 35 mm depth. Spring terminals reduce wiring time and eliminate the need for periodic re-torquing on the panel wireman's checklist.","metaTitle":"TeSys K LA1KN133M Auxiliary Contact Block, 1NO+3NC, Obsolete","metaDescription":"LA1KN133M TeSys K auxiliary contact block, 1NO+3NC, front mount, spring terminals.
