Bussmann 170M1756 – Frequently Asked Questions

1) What amp ratings does the Bussmann 170M-175 fuse link come in, and what is the part number for each?
The 170M-175 square body fuse link is offered in ten ratings from 25A to 350A: 25A (170M1750), 32A (170M1751), 40A (170M1752), 63A (170M1754), 80A (170M1755), 100A (170M1756), 160A (170M1758), 200A (170M1759), 315A (170M1761) and 350A (170M1762). Order by the amp rating you need, since everything else (750V DC, 200 kAIC, size 000 body) stays the same across the range.
2) Can I use the Bussmann 170M-175 to protect the semiconductors in a DC drive, or do I need a full-range fuse?
aR is a partial-range device: it clears short circuits to protect diodes, SCRs and IGBTs, but it is not intended to carry the overload duty on its own. Pair it with an overload protective device (drive electronics or a breaker) that handles low-level overcurrent. That is exactly what the aR utilization category, accompanied semiconductor protection, means.
3) Is the 170M-175 rated for DC only, or can I put it on an AC circuit?
The rating published for the 170M-175 fuse link is 750V DC. Use it on direct current circuits at or below 750 volts. If your application is AC, specify a fuse link with a stated AC voltage rating instead, because a DC rating does not transfer.
4) How does the 170M-175 fuse mount, and does it need a fuse holder?
It is a square body fuse link with offset bolted tags, so it bolts directly to busbar or to a bolt-down fuse base. There is no ferrule and no clip holder involved. You supply the bolts, washers and torque per your base or busbar detail.
5) Does the Bussmann 170M-175 come with insulated metal gripping lugs?
No. The standard configuration ships without IMGL. If your panel detail calls for insulated gripping lugs for touch-safety or handling, you will need to source those separately or specify a version that includes them.
6) What body size is the 170M-175, and will a 350A fit the same footprint as a 25A?
All ratings use the size 000 square body. For reference, the 100A option is 24 x 36 x 96 mm. Because the body size is common across the range, you can change amp rating within 25A to 350A without changing the mounting footprint, which is useful when you are standardizing bases across a plant.
7) What kind of equipment is the 170M-175 fuse link typically used in?
Typical duty is semiconductor and power electronics protection: DC drives and motor control, solar and renewable DC circuits, industrial power conversion gear, and traction or rail DC power. All of those are DC applications at or below 750 volts where a rectifier or inverter stack needs dedicated short-circuit protection.
8) How is the 170M-175 packaged for stocking spares?
Packaging type is standard, with each amp rating carried as its own part number. For MRO stocking, the practical approach is holding the ratings actually installed in your equipment, for example 160A (170M1758) and 200A (170M1759), since the fuse links are not interchangeable across ratings.
