Bussmann 170M4464 – Frequently Asked Questions

1) Is the Bussmann 170M4464 the right fuse for protecting semiconductors like IGBTs and SCRs?
Yes. The 170M4464 is a high speed fuse built for semiconductor protection, with utilization category aR, meaning accompanied semiconductor protection. aR is a partial range fuse: it clears high fault currents but does not protect against low level overloads, so the drive or converter still needs separate overload protection. It carries a 500 A rating.
2) What body style and mounting does the Bussmann 170M4464 square body fuse use?
It's a square body fuse with flush end contacts, mounted flush, so it bolts directly onto flat busbar or a flush base rather than dropping into a clip or blade holder. If your existing gear is set up for tag or offset tag terminals, the flush contact version will not line up.
3) What I2t values do I use to coordinate the Bussmann 170M4464 with my rectifier diodes?
Use 25,000 A2s pre-arc and 170,000 A2s clearing at 660 V for the 170M4464. The semiconductor's own I2t withstand has to exceed the fuse clearing I2t at your operating voltage for the device to survive a fault.
4) What are the dimensions and weight of the Bussmann 170M4464 fuse?
The 170M4464 measures 70 mm long, 51 mm wide and 51 mm high, and weighs roughly 788 g. Check that against the clearance in your fuse compartment before ordering, especially where several fuses sit side by side on a busbar.
5) How much heat does the 170M4464 fuse put into the enclosure?
Watt loss is 72 W at rated current. That is real heat inside a sealed cabinet, so size ventilation or forced cooling accordingly and derate the fuse if the compartment runs hot or airflow is restricted.
6) Can the Bussmann 170M4464 handle a high available fault current at the drive input?
Its interrupting rating is 200 kAIC, which covers most industrial services feeding large drives and converters. The fuse is AC rated.
7) Is the Bussmann 170M4464 approved for use in North American and European panels?
It is UL Recognized and CE Marked, so it can be used in listed assemblies in North America and in CE marked equipment for export. UL Recognized means it is a component approval, evaluated for use inside end equipment rather than as a standalone listed device.
8) What part number should I order to replace this Eaton high speed square body fuse?
Order Bussmann 170M4464. It is the genuine Eaton 170M series part number, a 500 A Class aR square body fuse with flush contacts, and it ships as standard packaging rather than a multi-pack.
9) Does the 170M4464 come with insulated metal gripping lugs for safer handling?
No. The 170M4464 is supplied without insulated metal gripping lugs (IMGL), so it is handled by the body. Plan on de-energizing and using standard PPE for changeout rather than pulling it live by a gripping lug.
