Bussmann 170M7028 – Frequently Asked Questions
1) Can I use the Bussmann 170M7028 as a general branch circuit or motor overload fuse?
No. The 170M7028 is a Class aR fuse, utilization category aR, which means accompanied semiconductor protection. An aR fuse only handles short circuit current and has to be backed up by another device for overload protection. For general feeder or motor circuit protection you want a gG/gL or a UL Class J, L or RK fuse instead. Use the 170M7028 where it belongs: across SCRs, diodes and thyristors in rectifiers, drives and converters.
2) Will a 2500A 690V fuse work on my 480V drive?
Yes on voltage. The 170M7028 is rated 690 V AC, and a fuse may be applied at or below its voltage rating, so a 480 V AC system is within range. The 690 V rating is there for 600/690 V industrial drive and rectifier systems. Do not apply it on DC without the manufacturer's DC rating, since the rating stated is AC.
3) Does the Bussmann 170M7028 come with insulated metal gripping lugs?
No. The 170M7028 is supplied without insulated metal gripping lugs (IMGL), so the terminal blades are bare bolt-down tags. If your installation needs insulated grip terminals or extra creepage at the connection point, plan on the alternate IMGL version of the body style rather than this one.
4) Does the 170M7028 have a microswitch or blown fuse indicator?
The 170M7028 carries an indicator, listed as an Other type rather than a standard striker or visual flag. If your panel uses a striker-operated microswitch for remote blown fuse signalling, confirm the indicator style matches your existing switch assembly, because the 170M series is offered with several indicator configurations and they are not interchangeable.
5) What kind of equipment does the Bussmann 170M7028 belong in?
It is a high amperage semiconductor fuse for power conversion gear: rectifier and converter banks, industrial motor drive systems, and heavy-duty AC distribution running up to 690 V. At 2500 A it sits on the main DC link or the AC line side of a large drive or rectifier, protecting the SCRs, diodes and thyristors downstream, not the load itself.
6) What part number do I order for this Bussmann 2500A semiconductor fuse, and how is it packaged?
Order by manufacturer part number 170M7028, from Bussmann. It ships in standard packaging as a single fuse. There are no size, voltage or indicator options to specify, the part number is the complete configuration.
