Bussmann 170M3468 – Frequently Asked Questions

1) Will the Bussmann 170M3468 fit my existing fuse holder, and what are its body dimensions?
The 170M3468 is a square body fuse with flush end contacts, so it bolts flat to busbar or holder pads rather than clipping in. Body size is 50 mm high, 60 mm long/deep and 43 mm wide, and it weighs 267 g. Check your mounting centers against the flush-contact pattern before ordering, since a clip-style or blade-style holder will not take it.
2) Is a Class aR fuse like the 170M3468 the right choice to protect an IGBT or SCR drive, or do I need gR?
Class aR is partial-range semiconductor protection, meaning it handles short circuit faults alongside another device that covers overload. The 170M3468 is an aR fuse, so it is intended to work with a drive's own overload protection or an upstream device. If you need a single fuse covering both overload and short circuit on the semiconductor, that is full-range gR/gS duty, not this part.
3) Can I use the Bussmann 170M3468 on a 690V AC industrial drive?
Yes. The 170M3468 is rated 690 V IEC (700 V UL) on AC. It is an AC-rated part, so do not apply it to a DC link or battery circuit on the strength of this rating.
4) What I2t values do I need to coordinate the 170M3468 with my semiconductor's withstand rating?
Clearing I2t is 68,500 at 660 V and pre-arc I2t is 40. Compare the clearing figure against the I2t withstand of the SCR or diode module you are protecting; the fuse only protects the device if its clearing I2t is below the semiconductor's rating at your applied voltage.
5) What fault current can the 170M3468 interrupt?
200 kAIC. That covers most high fault-current industrial services, so on a 690V bus fed by a large transformer this 350A high-speed fuse still clears without you needing a series-rated upstream device for interrupting capacity alone.
6) How much heat does this fuse put into the enclosure?
Rated watt loss is 64 W at full load. On a multi-fuse drive panel that adds up fast, so include it in your enclosure heat calculation and allow airflow around the flush-mounted body. Continuous loading well below the 350A rating reduces it.
7) Is the Bussmann 170M3468 CE marked and IEC rated for a European-built machine?
Yes, it is IEC rated and CE marked, which is what a machine builder exporting to the EU generally needs on the fuse line item. It also carries a UL voltage rating of 700V alongside the 690V IEC figure.
8) Does the 170M3468 have a blown-fuse indicator or microswitch for remote monitoring?
The indicator type on the 170M3468 is listed as Other, not a standard striker or microswitch option, so do not plan a remote trip signal around it. If your panel needs fuse monitoring, specify a 170M part built with a microswitch indicator instead.
9) Does this Bussmann fuse come with insulated gripping lugs?
No. The 170M3468 is supplied without insulated metal gripping lugs (IMGL), so it is a bare flush-contact square body fuse. If your spec calls for IMGL for safer handling or added clearance, you need a different 170M variant.
10) What exact part number do I order, and how is it packaged?
Order Bussmann (Eaton) 170M3468, the 350A 690V Class aR square body high-speed fuse. Packaging is standard, single-piece rather than a multipack, so quantity ordered equals fuses received.
