Bussmann 170M5163 – Frequently Asked Questions

1) Can I use the Bussmann 170M5163 as a branch circuit or motor overload fuse?
No. The 170M5163 is a Class aR high-speed fuse, utilization category aR meaning accompanied semiconductor protection. aR fuses only protect against short circuits, so they must be installed alongside another device (breaker or overload relay) that handles overload current. If you need overload plus short-circuit protection in one part, an aR high-speed fuse is the wrong choice.
2) Will the 170M5163 fit my existing square body fuse holder?
It is a square body fuse with slotted center bolted tags and blade end x blade end terminals built to the DIN 43 620 mounting standard, so it drops into DIN 43 620 blade-end mounting bases. Overall it measures 66 mm height x 286 mm length/depth x 165 mm width, which is what you need to check against your panel clearance. It does not have insulated metal gripping lugs, so plan on tools and de-energized work for removal.
3) What voltage and current is the Bussmann 170M5163 rated for?
700 A continuous at 700V AC under UL and 690V AC under IEC, with a 200 kAIC interrupt rating. The AC rating is the only one given, so do not apply it to a DC link without the manufacturer's DC data.
4) What I2t values do I need to coordinate this fuse with my SCRs or diodes?
For semiconductor coordination the 170M5163 publishes a pre-arcing (melting) I2t of 60,500 A2s and a total clearing I2t of 405,000 A2s at 660 V. Your thyristor or diode I2t withstand must exceed the clearing figure at your working voltage. Clearing loss is listed at 95.
5) Is this the right fuse for a variable frequency drive or rectifier front end?
Yes, that is the intended use. The 170M5163 is a high-speed semiconductor protection fuse for industrial drives, rectifier bridges, power conversion and motor control equipment. It clears fast enough to protect the silicon, which a standard Class J or Class T fuse will not do. Pair it with your drive's overload protection since the aR category only covers short circuits.
6) How do I tell if a Bussmann 170M5163 has blown without pulling it out?
It carries a top-mounted fuse status indicator, so a visual check from the front of the panel tells you the fuse condition without unbolting the tags. Handy on drive cabinets where the fuse sits behind a bank of others.
7) Is the Bussmann 170M5163 UL listed and CE marked?
The 170M5163 is UL Recognized and CE Marked. Note that UL Recognized is a component recognition, not a standalone UL Listing, which matters if your AHJ or panel builder is looking for a Listed device.
8) What part number do I order for the 700A 700V Bussmann high-speed square body fuse?
The manufacturer part number is 170M5163, Bussmann by Eaton. It ships in standard packaging as a single fuse, so order one per phase you are protecting.
9) How much does the 170M5163 weigh for mounting and handling?
Roughly 619 g. At that mass and 286 mm long, it is a two-hand part on a bolted DIN 43 620 base, and the bolted tags should be torqued to your holder manufacturer's spec for a low-resistance joint.
