As a fusible disconnect, it relies on fusible elements to interrupt current, offering a defined isolation point for servicing, reducing arc flash risk, and helping operators comply with safe deenergization practices when work is performed on energized lines. The 3-pole configuration indicates three-phase operation, which means this switch is intended to interrupt power in three-phase circuits and manage multiple conductors within a single enclosure, simplifying wiring and maintenance in complex electrical feeds. With a 30-amp rating, it is suitable for protecting feeders or control circuits in settings where a dedicated safety disconnect is required, and its fusible design provides overload protection aligned with common low- to mid-range distribution requirements. The TH3221 designation identifies a General Electric heavy-duty fusible switch line item used to provide reliable isolation during maintenance while the accompanying fuses supply short-circuit protection and help ensure downstream equipment is protected from overload events.\u003c\/p\u003e\u003c\/div\u003e","brand":"General Electric","offers":[{"title":"New","offer_id":51691566170414,"sku":null,"price":102.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_67dc1439-aeaa-42f4-8c4c-885102c681ab.jpg?v=1769892234","url":"https:\/\/plgautomation.com\/products\/general-electric-th3221-heavy-duty-fusible-safety-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
