In an overload or fault condition, the fuses interrupt current flow, preventing damage to motors and wiring. When maintenance is needed, the switch handle provides an obvious open\/isolated state for safe service, and fuses can be replaced to restore protection quickly.\u003c\/p\u003e \u003ch2\u003eSpecifications at a glance\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e PT363\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 100A\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 600V\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 3-Pole\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eFused:\u003c\/strong\u003e Fusible\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eIdeal for:\u003c\/strong\u003e motor disconnects, panelboards, and branch circuit protection where a compact, maintainable fusible switch is required\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003ePractical tips for best results\u003c\/h2\u003e\n\u003cp\u003eTo maximize reliability, pair the PT363 with appropriately rated fuses that match your motor's full-load current, and plan for straightforward fuse replacement during routine maintenance. Always follow lockout\/tagout procedures during servicing, verify proper enclosure clearance, and ensure wiring gauge and conductor routing are suitable for 600V three‑phase feeds. This approach keeps downtime to a minimum while maintaining robust protection for critical equipment.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Amp-State","offers":[{"title":"Default","offer_id":46390407790754,"sku":"PT363","price":673.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/fusible_disconnect_generic_542bb4fc-ae6a-422b-b460-96f0b60fe6a4.png?v=1765370435","url":"https:\/\/www.ampstate.com\/products\/pt363-100a-600v-3-pole-fusible-disconnect-switch","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
