The S1N100TL provides protective interruption for distribution feeders in commercial and industrial power systems, helping guard circuits against overloads and short circuits within a compact molded-case form factor. With its 277\/480 VAC rating, this breaker aligns with common voltage classes used for large facilities, enabling reliable protection for feeders powering lighting, motors, and other three-phase loads in modern electrical installations. The bolt-on mounting configuration facilitates secure mechanical attachment to compatible bus systems and panel structures, supporting straightforward installation and replacement in ABB-compatible assemblies. Constructed as a molded-case circuit breaker, the S1N100TL combines durability with practical serviceability for maintenance and field swaps in controlled indoor panel environments. In practical terms, this model fits systems that require a 3-pole, 100 A protective device for 277\/480 VAC three-phase distribution, offering a clear, local means of interrupting power when protection is needed and integrating into layouts designed around S1N-type breaker footprints. For engineers selecting components, the S1N100TL provides a direct, standards-aligned option that matches the voltage class and phase configuration of many commercial power distribution schemes. \u003c\/p\u003e\u003c\/div\u003e","brand":"ABB","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46257216225514,"sku":null,"price":319.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-085.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/abb-s1n100tl-bolt-on-molded-case-circuit-breaker","provider":"GTG Hardware","version":"1.0","type":"link"}
