As part of the APL111-1 family, it combines power switching with protective trip in a sealed enclosure and supports configurations that include inverse-time delay behavior and optional auxiliary contacts or different terminal arrangements. The 4-1-602 designation identifies a specific configuration within this line, a variant used in aerospace equipment that requires reliable overload protection for high-frequency power rails. The device features trip-free operation, ensuring the circuit is reliably disconnected when tripped, and is suitable for protecting circuits in aircraft panels, avionics racks, and other equipment powered from 400 Hz systems. Depending on the sub-model, some variants offer quick-connect terminals to simplify wiring in tight installations, while others may use different terminal styles to match equipment harnesses. Airpax’s APL111-1 family is documented in Sensata catalogs and aerospace procurement references, reflecting its role in defense and aviation applications where robust, high-frequency protection is essential.\u003c\/p\u003e\u003c\/div\u003e","brand":"Airpax","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657157607726,"sku":null,"price":197.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_19c0eff1-816c-4f6d-99f6-ce17e9557ab1.jpg?v=1769466500","url":"https:\/\/plgautomation.com\/products\/airpax-electronics-apl-111-1-4-1-602-circuit-breaker-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
