The interlock housing is aluminum and features a lever‑style actuator with mounting provisions compatible with Square D EK safety switch assemblies in the E1–E2 family, with the -1 suffix denoting a single NO\/NC configuration. Designed as a field‑ or factory‑installable accessory, EK-300-1 supports safe interlock sequencing in industrial enclosures, guarding equipment against energization until the corresponding circuit is de‑energized, and it is intended for use on 30 A Class 3110 safety switches. Common applications include interlocking dual‑circuit safety devices and retrofits where a dedicated interlock is required to meet safety and code requirements, making EK-300-1 a standard, compatible choice among Square D interlock kits for 30 A safety switches.\u003c\/p\u003e\u003c\/div\u003e","brand":"Square","offers":[{"title":"New","offer_id":46259005980906,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-012.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/schneider-electric-ek-300-1-electrical-interlock","provider":"GTG Hardware","version":"1.0","type":"link"}
