Bussmann 170M6094 Eaton Series High-Speed Square Body Fuse, 130A Class aR

The Bussmann 170M6094 is an Eaton Bussmann series high-speed square body fuse rated 130A and 7200V AC, purpose-built for semiconductor protection in demanding industrial power systems. Classified as a Class aR (accompanied semiconductor protection) fuse, it combines a rugged square body with slotted offset bolted tags for secure, high-current connections. A top fuse status indicator provides fast visual confirmation of fuse condition, helping maintenance teams quickly identify a blown fuse without disrupting the circuit.

Bussmann 170M6094 – Frequently Asked Questions

1) Will the Bussmann 170M6094 fuse fit my existing fuse holder or bus mounting?
The 170M6094 is a square body fuse with slotted offset bolted tags, so it bolts directly to bus bar or stud terminations rather than dropping into a clip-style holder. Body envelope is 70 mm high by 70 mm wide with a 513 mm length/depth dimension, and it weighs 1893 g. The slotted tags give some tolerance on hole centers, but you need bolted terminations with room for that 513 mm span before you order.
2) What does Class aR mean on this Bussmann high-speed fuse, and can I use it as the only overcurrent protection?
aR stands for accompanied semiconductor protection. The 170M6094 is built to clear short circuits fast enough to save semiconductors, but an aR fuse only covers the short-circuit range. It is not intended to stand alone against sustained overloads, so the circuit still needs a separate overload device such as a breaker or relay working with it. If you want a device that handles both overload and short circuit, you want a full-range gR/gS type instead.
3) Can I use the Bussmann 170M6094 on a 4160V or 6.6kV AC drive circuit?
Yes on both counts. The 170M6094 carries a 7200V AC rating, so it covers medium-voltage AC applications at or below that level, including 4160V and 6.6kV systems. The rating is AC only, so do not apply it to a DC link or DC traction circuit on the strength of that number.
4) Is a 130A high-speed semiconductor fuse the right choice to protect an SCR rectifier stack?
That is exactly what the 170M6094 is for. Rated 130A, it is an Eaton Bussmann high-speed fuse for semiconductor protection, meaning it is sized to let through less I2t than the SCR or diode can withstand. Match the fuse I2t and peak let-through to the device rating, not just the amp number, and remember that a standard industrial class fuse of the same 130A will not clear fast enough to save the semiconductor.
5) How do I tell if this Bussmann square body fuse has blown without pulling it out?
There is a top-mounted fuse status indicator on the 170M6094. It gives a visual blown-fuse signal from above, so a maintenance tech can walk the line and check condition without unbolting the fuse or de-terminating the bus. It is a visual indicator only, not a microswitch output, so if you need a remote trip or alarm contact you will need a striker-type fuse with a microswitch.
6) Does the Bussmann 170M6094 come with insulated metal gripping lugs?
No. The 170M6094 is supplied without IMGL insulated metal gripping lugs. Termination is through the slotted offset bolted tags on the square body, so plan on your own bolt, washer and bus hardware to land it. Packaging is standard.
7) What part number do I order for the 130A 7200V Bussmann square body fuse?
Order Bussmann part number 170M6094. It is a single configuration, 130A at 7200V AC, Class aR square body with bolted tags and a top status indicator, so there are no handing, mounting or indicator variants to specify on the order.
8) Is the Bussmann 170M6094 heavy enough that mounting needs support?
At 1893 g with a 513 mm length dimension, this is a substantial bolted fuse, not something a flexible cable lug should carry. Land it on rigid bus or a properly braced fuse mount so the tags are not taking the weight or the vibration.
