It mounts on the front of the device and connects via lugs-ring terminals, making it a straightforward add-on for control-circuit feedback or interlocking. The making capacity of 110 A at 10 MOhm means it can close onto a cold load without welding contacts, which matters for solenoid or contactor coil circuits that draw a high inrush. Insulation voltage is rated at 690 V per IEC 60947-5-1, with operational voltage up to 690 V AC at 25–400 Hz. The IP20 finger-safe housing protects against accidental contact during maintenance — standard for control-gear inside a locked enclosure.
This block is sized for the TeSys K contactor footprint: 38 mm wide, 30 mm high, 35 mm deep. It clips onto the front of the contactor, adding no extra DIN-rail width — useful when panel space is tight and you need auxiliary contacts without expanding the rail footprint. The lugs-ring terminals accept ring or fork lugs, which stay secure under vibration on a machine or conveyor line.
The LA1KN226 carries approvals under EN/IEC 60947-5-1, UL 60947-5-1, CSA C22.2 No 60947-5-1, GB/T 14048.5, and JIS C8201-5-1. It also meets UL 60335-2-40 Annex JJ for household appliance applications. That means it is accepted in North American (UL/CSA), European (IEC/EN), Chinese (GB/T), and Japanese (JIS) markets — no separate regional variant needed for most control-panel builds. For BOM-freeze planning, this part is a standard catalog line with no imminent obsolescence risk.
