It is a 100A device configured for a double-throw transfer (I ⇄ II) with flexible terminal options that support front- or rear-mounted connections, and it includes provisions for manual operation during maintenance when the circuit is de-energized. Automatic switching requires an external control circuit that integrates a power-outage detection relay and related control logic, a common setup for reliable standby-power systems. This design targets critical-load applications—such as servers, industrial controls, and process equipment—where uninterrupted power is essential, and it can be augmented with standard W2 accessories like main-terminal covers and auxiliary switches to tailor installation to exact requirements.\u003c\/p\u003e\u003c\/div\u003e","brand":"Aichi","offers":[{"title":"New","offer_id":51657138536750,"sku":null,"price":464.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_7d86eac4-5111-4830-80d0-3d539d5a45c4.jpg?v=1769466316","url":"https:\/\/plgautomation.com\/products\/aichi-electric-21v2-2fd-e-automatic-transfer-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
