Schneider Electric EIK1 Interlock Safety Switch

Schneider Electric’s Square D EIK1 interlock safety switch is a field‑installable interlock kit for disconnect switches, engineered for 100 A to 200 A general‑duty safety switches in the Series F family and compatible heavy‑duty switches (F5/F6/F7). It provides one normally open and one normally closed contact (SPDT), enabling interlock and sensing in control circuits, and is rated for up to 600 V AC/DC. This kit is designed to be installed with standard safety switch enclosures to help ensure safe isolation of equipment in industrial applications, connecting to the safety switch’s actuation to reflect interlock status in the control logic. The EIK1 is part of Schneider Electric’s interlock kit lineup alongside the EIK2 option, and is commonly specified when a field interlock is required on 100–200 A general‑duty configurations for enhanced machine safety and compliance in motor control and process environments.
