It is designed to interlock a companion disconnect or feed a control circuit, enabling safe sequencing in safety-switching configurations. Compatible with Square D Series E1–E2 heavy‑duty disconnect switches and commonly used with Class 3110 safety switches, the EK300-1 attaches to the disconnect to provide electrical interlock signaling without replacing the main operating mechanism. The -1 suffix denotes a single interlock with 1 NO and 1 NC contact, offering simple integration into control circuits and interlock logic.\u003c\/p\u003e\u003c\/div\u003e","brand":"Square","offers":[{"title":"New","offer_id":46259006275818,"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-ek300-1-electrical-interlock","provider":"GTG Hardware","version":"1.0","type":"link"}
