KTU-850 - 850Amp Fuse

KTU-850 - 850Amp Fuse

The Eaton Bussmann KTU-850 is an 850A Class L fuse rated for 600V, with a 200 kAIC interrupt rating at 600 VAC. It features bolt mounting, is non-indicating, and has a ferrule design with a melamine glass tube and silver-plated end bells. When performing maintenance or replacement, compare the catalog number, Class L classification, amperage, voltage, interrupt rating, mounting method, and dimensions with your existing fuse to ensure a proper fit.

Key Features and Benefits

• 850A amperage rating — an essential specification to verify against the equipment requirements.
• 600V voltage rating — clearly identified for straightforward replacement comparisons.
• Class L classification — makes the fuse class easy to confirm when reviewing maintenance records or equipment documentation.
• Bolt mounting method — another practical physical detail to check before installation.
• Ferrule design — listed by the manufacturer as the KTU-850's special feature.
