Bussmann 170M3464 – Frequently Asked Questions

1) Can I use the Bussmann 170M3464 fuse for general branch circuit or motor protection?
No. The 170M3464 is a Class aR high-speed fuse, which is partial-range semiconductor protection. Class aR clears short circuit fault currents only, so it will not protect against sustained overloads. It has to be used alongside a device that handles overload duty (a breaker, overload relay, or drive electronics). For general-purpose overcurrent protection on a feeder or motor circuit, use a full-range fuse class instead.
2) Will the 170M3464 fit my existing square body fuse holder?
It is a square body fuse with flush end contacts, so it mounts flush into a semiconductor fuse block rather than bolting through with offset blade tags. Body dimensions are 60 mm length/depth, 50 mm height and 43 mm width. Check those against the block you have, and note it does not have insulated metal gripping lugs, so if your existing fuse uses IMGL tags this is not the same mounting style.
3) Is a 700V fuse OK on a 690V AC drive?
Yes. The 170M3464 carries a 690V IEC AC rating and 700V under UL, so it suits 690V AC power electronics circuits. It is an AC-rated part; the listed rating does not cover DC applications, which have their own voltage ratings on high-speed fuses.
4) How do I know this fuse will actually protect my SCR or diode module?
Coordinate on I2t. The 170M3464 has a pre-arc I2t of 1100 and a total clearing I2t of 7500 at 660V. Compare the clearing value at your circuit voltage against the I2t withstand figure on the semiconductor datasheet; the fuse value has to come in below the device withstand. It is intended for SCRs, diodes and power modules in rectifier, inverter and drive equipment.
5) What heat load does a 160A Bussmann 170M3464 add inside an enclosure?
34 W at rated current. For panel thermal calculations, multiply that by the number of fuses in the enclosure and add it to the drive and contactor losses. Square body high-speed fuses run hot at full load, so allow ventilation clearance around the fuse block and derate per the fuse block and ambient conditions.
6) Is 200 kAIC enough for my service, and what does that rating mean here?
The 170M3464 interrupts up to 200,000 A of available fault current, which covers most industrial services fed from large transformers. As a current-limiting fuse it also cuts the let-through energy well below the prospective fault current, which is the point of using it ahead of semiconductors rather than relying on a breaker alone.
7) Is the Bussmann 170M3464 acceptable on a CE-marked machine going to Europe?
Yes. It is IEC rated and CE marked, and the 690V IEC rating is the figure to use on European machine documentation rather than the 700V UL number.
8) Does the Bussmann 170M3464 have a blown fuse indicator or microswitch?
The indicator type on the 170M3464 is listed as Other, not a standard striker or microswitch option, so don't plan a remote blown-fuse alarm circuit around this part number. If you need monitored indication, specify a 170M series fuse ordered with the indicator/microswitch option.
9) How is the 170M3464 packaged and what part number do I order?
Order by manufacturer part number 170M3464, supplied in standard packaging as a single fuse. Spares are usually stocked one per protected phase leg, so a three-phase rectifier bridge typically takes three.
