Obsolete — sourced to order
Schneider Electric lists the LA1KN22P as Obsolete. No direct replacement or successor part number is provided by the manufacturer. This part is available through independent surplus channels; quantities are lot-specific and confirmed at RFQ. No pin-compatible alternative is recorded from the original manufacturer.
2 NO + 2 NC, front-mount, screw terminals
The LA1KN22P is a TeSys K auxiliary contact block with a 2 NO + 2 NC pole contact composition. It mounts on the front of a TeSys K contactor, adding four instantaneous auxiliary contacts for signaling or interlock circuits. The screw clamp terminals accept 1.5 mm² flexible with cable end, 4 mm² flexible without cable end, or 4 mm² rigid wire. Tightening torque is 1.3 N.m using a Philips No 2 or Pozidriv No 2 driver.
Electrical ratings and environmental specs
Rated operational voltage (Ue) is 690 V AC at 25...400 Hz. Conventional free air thermal current (Ith) is 10 A at 50 °C. Making capacity is 110 A at 10 MOhm. IP20 degree of protection per IEC 60529 means finger-safe but not sealed against moisture — suitable for dry indoor panel environments. Maximum operating altitude is 2000 m.
Panel fit: dimensions and mounting
Dimensions are 1.5 in (38 mm) wide, 1.2 in (30 mm) high, and 1.4 in (35 mm) deep. The front-mount design clips onto the contactor without additional DIN-rail space — the contactor itself occupies the DIN rail slot. The block adds negligible panel depth beyond the contactor body. Protective treatment conforms to TC IEC 60068.
