Eaton 170M3473 Fuse

170M3473 is an Eaton Bussmann high-speed fuse with a square-body design rated for 630 A and 690 V AC (IEC), with a UL rating of 700 V. This compact size (catalog designation 1*BKN/50 AR UC) features a single indicator and is part of Eaton’s Bussmann Series of high-speed fuses, designed to interrupt faults quickly in demanding power circuits found in control panels, motor drives, and industrial equipment. The fuse carries dual listings under IEC and UL specifications, enabling reliable protection in mixed-spec installations where high current and high voltage are present, all in a form factor that fits tighter panel spaces. In 630 A rating implementations, the 170M3473 provides a robust protective solution without excessive footprint, making it a common choice for applications requiring fast-acting protection on large feeders or critical loads.
