Bussmann 170M1408 – Frequently Asked Questions

1) What amp ratings does the Bussmann 170M-136 square body fuse come in, and what is the part number for each?
The 170M-136 family covers 10A through 63A. The orderable ratings are 10A (170M1408), 16A (170M1409), 20A (170M1410), 25A (170M1411), and 63A (170M1365). Amp rating is the only thing you choose; voltage, body style, and class are the same across all five.
2) Will a Bussmann 170M-136 fuse fit my existing square body semiconductor fuse holder?
It is built to the DIN 43 620 square body mounting standard with slotted offset bolted tags and blade end x blade end terminals, so it mounts in holders and busbar arrangements prepped for that standard. Body dimensions are 300 mm width, 105 mm length/depth, and 46 mm height. Check your holder or bus spacing against those numbers before ordering.
3) Can I use a 170M-136 high-speed fuse for general branch circuit or motor overload protection?
No. It is a Class gR semiconductor fuse, meaning it is built to clear fast enough to protect diodes, SCRs, IGBTs and similar devices in power electronics. Use it for rectifier and converter protection, drive DC links, and semiconductor stacks. Branch circuit and motor overload duty calls for a conventional Class J, RK, or CC branch circuit fuse instead.
4) What voltage and fault current can the Bussmann 170M-136 handle?
Rated 700V AC under UL and 690V AC under IEC, with a 200 kAIC interrupting rating. That covers 480V and 600V industrial drive and converter systems on high fault-current services. It is an AC rating, so do not apply it to a DC circuit on the strength of these numbers.
5) I need to replace a blown fuse in a drive cabinet. How do I pick the right 170M-136?
Match the amp rating stamped on the old fuse to one of the five available: 10A, 16A, 20A, 25A, or 63A. Everything else in the family is fixed, 700V UL, 200 kAIC, gR class, DIN 43 620 square body with blade ends. If the fuse you pulled is a different body length or a bolt-in tag style, it is not a drop-in and you need the matching 170M variant for that holder.
6) How do I tell if a 170M square body fuse has blown without pulling it out of the holder?
These carry a top-mounted fuse status indicator, so a tech can confirm the condition visually from the front of the panel during troubleshooting. If your panel layout blocks the top face, plan for a microswitch-equipped version instead, since this one relies on the visual indicator alone.
7) Is the Bussmann 170M-136 acceptable on a UL-listed panel build?
It carries both UL and IEC listings, at 700V and 690V respectively, and the body conforms to DIN 43620. That combination is what lets the same fuse be specified on North American UL panels and on export equipment built to IEC rules.
8) Does the Bussmann 170M-136 have insulated metal gripping lugs?
No, the 170M-136 is supplied without IMGL. The terminations are plain blade ends that bolt down to the bus or holder, so if your install spec calls for insulated gripping lugs you need a different variant of the 170M line.
