It switches 6 A in AC-3 or AC-1 duty and makes 66 A at 690 V AC per IEC 60947. Compared to the LC1SKGC310G7 three-pole contactor rated 20 A switching and 85 A making capacity, the LA1SK01 is a lower-current add-on block (6 A, 66 A making) meant to extend an existing contactor's pole count or add a signalling contact, not to replace a main power contactor. Schneider lists the LA1SK01 as active production; no end-of-life notice. Standard lead time applies; an RFQ confirms current availability.","metaTitle":"Schneider LA1SK01 TeSys SK power add-on block, 1NO+1NC","metaDescription":"Schneider LA1SK01 TeSys SK power add-on block: 1 NO power contact, 1 NC signalling contact, 6 A switching current, 66 A making capacity at 690 V AC, AC-3/AC-1, active.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Control Accessories"],"specifications":{"Range":"TeSys","Category":"22371-RELAYS, CONTROL","Standards":"EN/IEC 60947-4-1 UL 60947-4-1 CSA C22.2 No 60947-4-1","Product name":"TeSys SK","lifecycle_stage":"current","Device short name":"LA1SK","Tightening torque":"7.08 lbf.in (0.8 N.m) connector pozidriv No 1","Operating altitude":"6561.68 ft (2000 m) without derating","Protective treatment":"TC IEC 60068 TC DIN 50015","Utilisation category":"AC-3 AC-1","Nbr. of units in pkg.":"1","Associated fuse rating":"16 A gI at 10 A gI for signalling circuit conforming to IEC 60947 10 A gI for signalling circuit conforming to VDE 0660","Connections - terminals":"connector 1 0.0005...0.009 in² (0.35...6 mm²)flexible with cable end connector 1 0.0008...0.009 in² (0.5...6 mm²)flexible without cable end connector 1 0.002...0.009 in² (1.5...6 mm²)solid connector 2 0.0005...0.002 in² (0.35...1.5 mm²)flexible with cable end connector 2 0.0005...0.004 in² (0.35...2.5 mm²)flexible without cable end connector 2 0.002...0.006 in² (1.5...4 mm²)solid","IP degree of protection":"IP2X VDE 0106","Pole contact composition":"1 NO","Product or Component Type":"Power add-on block","Irms rated making capacity":"66 A at 690 V AC conforming to IEC 60947 66 A at 690 V AC conforming to NF C 63-110","Signalling circuit frequency":"<= 400 Hz","Auxiliary contact composition":"1 NC","[Ui] rated insulation voltage":"690 V IEC 60947 690 V VDE 0110 group C 690 V BS 5424 690 V UL 508 690 V CSA C22.2 No 14","Power Pole Contact Composition":"1P","[Ie] rated operational current":"6 A at 12 A (at <131 °F (55 °C)) AC AC-1 for power circuit","[Ue] rated operational voltage":"Signalling circuit 690 V AC Power circuit 690 V AC 50/60 Hz","Ambient Air Temperature for Storage":"-58...158 °F (-50...70 °C)","Ambient Air Temperature for Operation":"-4...122 °F (-20...50 °C)","[Icw] rated short-time withstand current":"50 A 131 °F (55 °C) for power circuit","[Ith] conventional free air thermal current":"12 A (at 131 °F (55 °C)) for power circuit 10 A (at 131 °F (55 °C)) for signalling circuit"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$16.04","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/d366b0a1148f02c1e79c8a26d1f58152.pdf","sourceUrl":"https://www.se.com/nl/en/product/LA1SK01/tesys-sk-power-add-on-block-1no-power-1nc-signalling/"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/LA1SK01","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/LA1SK01 when reusing this data.
