Bussmann 170M2107 – Frequently Asked Questions

1) Can the Bussmann 170M-210 fuse-link be used on an AC circuit, or is it DC only?
The 170M-210 is rated 1200V on DC. Its voltage type is stated as DC, so specify it for DC traction and third-rail circuits. For an AC semiconductor circuit, choose a fuse-link whose rating is published for AC service instead.
2) What amp ratings does the Bussmann 170M-210 fuse-link come in, and what part number do I order?
Six ratings across the family: 20A (170M2100), 40A (170M2103), 100A (170M2107), 160A (170M2109), 200A (170M2110) and 215A (170M2111). All share the same 1200V DC rating and square body size 1 form, so the amp rating is the only thing you pick when ordering.
3) Is a Class aR fuse the right choice for protecting my DC drive semiconductors, or do I need gR?
Class aR is a partial-range semiconductor fuse: it protects against short circuit faults only and is meant to work alongside another device that handles overload. That is the 170M-210's utilization category, stated as aR, accompanied semiconductor protection. If you need one fuse to cover both overload and short circuit on its own, you want a full-range gR or gS type rather than this one.
4) Will the 170M-210 clear a fault on a system with high available short-circuit current?
It carries a 50 kAIC interrupt rating, so it is suitable where available fault current at the fuse location does not exceed 50 kA. Rated switching capacity is 150 A. Confirm your system study's available fault current against that 50 kA figure before you specify it.
5) How does the Bussmann 170M-210 mount in a fuse holder or busbar?
Mounting is bolted, not clip-in. The body is square with offset bolted tags, so it lands on drilled busbar or a bolt-down base rather than a cylindrical fuse clip. Plan for bolt hardware and clearance to the tag offset in the panel layout.
6) Does the 170M-210 fuse-link meet IEC standards for a European or transit spec?
It is built to IEC 60269-4, the standard for fuses protecting semiconductor devices, and is CE compliant. Those are the two compliance points stated for the 170M-210 family.
7) How do I tell if a 170M-210 fuse has blown without pulling it out?
Each fuse-link has a single built-in indicator that pops to show the element has operated, so a maintenance tech can check status visually at the panel. It does not provide a remote signal contact on its own.
8) Is the 170M-210 a compact enough fuse for a tight traction power cubicle?
It is a size 1 square body, the smaller end of the bolted square body range, which is why it turns up in space-constrained traction and third-rail enclosures. Leave room for the offset bolted tags when you lay out bus spacing.
