Bussmann 1B0089 Eaton Series Class T Modular Fuse Block, 200A, 600V

The Bussmann 1B0089 is an Eaton series Class T modular fuse block engineered for reliable overcurrent protection in demanding electrical distribution systems. Built with a Glass Polyester body for excellent dielectric strength, this modular fuse block accommodates fuses rated 101-200A at 600 Vac, 600 Vdc, with a 200 kAIC interrupt rating for high short-circuit fault current environments. Box lug connections and a #6-250 kcmil Cu/Al wire range make it suitable for heavy industrial and commercial conductor terminations.

Key Features

  • Amperage Rating: 101-200A fuse capacity supports high-current commercial and industrial power distribution circuits.

Bussmann 1B0089 – Frequently Asked Questions

1) What wire size can I land on the Bussmann 1B0089 Class T fuse block?
Box lug terminals take #6 AWG through 250 kcmil, and they are rated for both copper and aluminum conductors. That covers most feeder terminations at the 200A level without an adapter lug. If your conductor is smaller than #6 or you are running parallel sets above 250 kcmil, this block is the wrong termination.
2) Is a 200 kAIC fuse block enough for a high fault current service?
The 1B0089 carries a 200 kAIC interrupt rating, which is the top tier normally specified for service entrance and motor control center locations where available fault current is high. Confirm the fault current at your point of application against the engineer's study, but 200 kAIC covers the large majority of commercial and industrial distribution equipment.
3) Can I use this Bussmann fuse block on a DC circuit?
Yes. The 1B0089 is rated 600 Vdc as well as 600 Vac, so it works in DC distribution such as drive and battery systems as well as standard AC panels. Match the fuse itself to the DC rating too, since not every Class T fuse carries a 600 Vdc rating.
4) Why choose a Class T fuse block over Class J for a 200A feeder?
Class T is the compact choice. Class T fuses have a notably smaller footprint than Class J or Class R at the same amperage, which is why they show up in tight switchgear, meter stacks, and motor control centers where panel space is the constraint. The 1B0089 is built for that: Class T, 101-200A, 600 V, with a 200 kAIC rating. If you have room and the drawing calls for Class J time delay, use a Class J block instead; the fuse bodies are not interchangeable.
5) Does the Bussmann 1B0089 come with fuses?
No. The 1B0089 is the modular fuse block only, the base that mounts in the panel and holds the fuses. Order the Class T fuses separately, sized within the 101-200A band and rated for your system voltage up to 600 V.
6) Can I gang Bussmann 1B0089 blocks together for a three-phase circuit?
It is a modular block, which is the design intent: single-pole modules are assembled side by side to build the pole count the circuit needs, so three of them make up a three-phase set. Order one module per pole.
7) What is the Bussmann 1B0089 fuse block body made of, and does it hold up in a hot panel?
The body is glass polyester, a thermoset used for its dielectric strength and heat resistance in fused distribution gear. That is the standard material for Class T blocks handling 600 V and heavy feeder conductors, rather than a molded thermoplastic.
