BUSSMANN 170M2657 Fuse

The BUSSMANN 170M2657 is a semiconductor high‑speed fuse in a square body, rated for 35 A at up to 690 V (AC). Part of Eaton's Bussmann 170M family, the 170M2657 variant uses a 00TN/80 AR termination and is commonly listed as "FUSE SQUARE 35A 690V 00TN/80 AR" by distributors. This fuse is designed to protect power electronics and electrical circuits in industrial equipment from overcurrent, with the fast-acting characteristics typical of square‑body high‑speed fuses used in panels, drives, rectifier circuits, and other semiconductor loads. The 170M series is documented across Bussmann's catalogs and retailer listings, confirming its form factor, rating, and termination style for installation in control panels and power distribution enclosures. The combination of a square‑body package, 35 A rating, and 690 V rating makes it suitable for protecting sensitive components and preventing damage from fault currents in environments where reliable, fast-acting protection is required.
