Product details

Overview

The LA1SK01 is a TeSys SK power add-on block from Schneider, adding one normally-open power pole and one normally-closed signalling contact to a TeSys SK miniature contactor base. 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.
