Bussmann 170M3413 – Frequently Asked Questions

1) Will a Bussmann 170M-340 fuse fit my existing square body fuse block?
The 170M-340 is a square body fuse with flush end contacts, and the body measures 155 mm length/depth by 90 mm wide by 45 mm high. Flush end contacts mean it bolts flat against the block face rather than using metal gripping lugs, so your holder has to be prepped for flush mounting. This version does not have insulated metal gripping lugs (IMGL), so if your existing installation uses an IMGL-style mount, this is not a drop-in.
2) Can I use a Class aR semiconductor fuse for branch circuit or motor overload protection?
No. Class aR is an accompanied semiconductor protection rating, meaning the 170M-340 is a partial-range device that clears short circuits only. It has to work alongside another protective device that handles overload and low-level fault currents. If you need full-range protection that also covers overloads, you want a gR/gS type fuse or a circuit breaker in the same circuit, not this one on its own.
3) What amp ratings does the Bussmann 170M-340 come in, and what are the part numbers?
The 170M-340 family covers 40A through 630A. The orderable ratings are 40A (170M3408), 125A (170M3413), 200A (170M3415), 250A (170M3416), 315A (170M3417), 350A (170M3418), 400A (170M3419), 450A (170M3420), 500A (170M3421) and 630A (170M3423). All share the same square body size, so you can step up or down in rating without changing the fuse block.
4) Is a 700V fuse acceptable on a 480V or 600V drive?
Yes. The 170M-340 is rated 700V under UL and 690V under IEC, and a fuse may be applied at or below its voltage rating. That covers 480V and 600V industrial drive circuits. Do not apply it above 700V. The dual UL/IEC rating is why this one gets specified on equipment built in North America and shipped overseas.
5) How do I tell if a 170M-340 has blown without pulling it out of the panel?
There is a top-mounted fuse status indicator on the body. A maintenance tech can check the condition visually from the front of the panel, no removal and no meter needed. That matters on multi-fuse rectifier and drive assemblies where pulling each fuse to test it is the slow part of the troubleshoot.
6) Is the Bussmann 170M-340 fuse CE marked for export equipment?
Yes, the 170M-340 is CE marked, and it carries both UL and IEC voltage ratings (700V UL, 690V IEC). That combination is what lets an OEM build one panel design and ship it into both North American and European installations.
7) Does the amp rating change the physical size of the 170M-340 fuse?
No. Every rating from 40A to 630A in the 170M-340 family shares the same square body: 155 mm length/depth, 90 mm wide, 45 mm high. Rerating a panel within that range is a fuse swap, not a block or bus rework.
8) What kind of equipment is the 170M-340 normally used in?
It protects semiconductors, not wiring. Typical spots are variable frequency motor drives, rectifier and power conversion stacks, solar and other renewable energy inverters, and switchgear fuse blocks on high fault current industrial panels. If your load is a transformer, lighting, or general feeder, a high-speed aR fuse is the wrong tool and a standard Class J or RK fuse is the right one.
