Eaton BK/SC-1-1/2 Fuse - Class G, 100 kAIC at 600 Vac
Part Number: BK/SC-1-1/2
Quick Summary
The Eaton Bussmann BK/SC-1-1/2 fuse is a current-limiting fast-acting device used for branch circuit protection. Engineers often struggle to balance small form factors with the high interrupt ratings needed for HVAC and control-panel circuits. RoHS compliant and built to Class G specifications with a rejection-style, non-indicating design, it supports quick field checks and safer maintenance. Bulk packaging and compact dimensions (1.31 in L) help reduce inventory footprint while enabling reliable HVAC branch circuit protection. With a 1.5 A rating and interrupt ratings of 100 kAIC at 600 Vac and 10 kAIC at 170 Vdc, it delivers robust protection under short-circuit events while supporting easy installation in standard bulk packaging.
