Bussmann 170M-415 High Speed Square Body Class aR Fuse, 690V 200kAIC

The Bussmann 170M-415 High Speed Square Body Fuse is an Eaton Bussmann series fuse engineered for demanding semiconductor protection applications, available in 11 selectable amp ratings from 200A to 800A. Rated 690V with a 200 kAIC breaking capacity, this Class aR (accompanied semiconductor protection) fuse features a square body with centre-bolted tags (slotted M4) and blade end x blade end terminals built to DIN 43 620 dimensional standards. A top-mounted fuse status indicator gives installers a fast visual check of fuse condition, and the AC-rated construction suits industrial power electronics and drive systems.

Bussmann 170M4158 – Frequently Asked Questions

1) Will the Bussmann 170M-415 square body fuse mount in a standard DIN fuse holder?
Yes. The 170M-415 is built to DIN 43 620 mounting dimensions with a square body and slotted, centre-bolted tags, so it drops into holders and disconnects prepped for that standard footprint. The terminal arrangement is blade end x blade end, and the body measures 245 mm by 142 mm by 62 mm, so confirm your holder centres and enclosure clearance against those figures before you order.
2) What amp ratings can I get the Bussmann 170M high speed square body fuse in?
Orderable amp ratings run 50A (170M4176), 200A (170M4158), 250A (170M4159), 315A (170M4160), 350A (170M4161), 400A (170M4162), 450A (170M4163), 500A (170M4164), 550A (170M4165), 630A (170M4166), 700A (170M4167), 800A (170M4168) and 900A (170M4019). Amp rating is the only thing you select; voltage, body size and terminal style stay the same across the group.
3) Can I use a Class aR semiconductor fuse as the only overcurrent protection on a drive circuit?
No. Class aR is an accompanied semiconductor protection rating, meaning the fuse clears short circuits fast enough to save thyristors and diodes but is not intended to handle overload protection on its own. It has to work alongside a device that covers overload, typically the drive's own electronic protection or an upstream breaker. If you need a fuse that covers both overload and short circuit, you want a full-range gR or gS type instead.
4) Is the Bussmann 170M-415 fuse rated for 690V AC drive systems?
It is an AC-rated fuse at 690V with a 200 kAIC interrupting capacity, which covers typical 690V industrial drive and rectifier switchgear where available fault current is high. Do not apply it on DC links or DC output sections; the published rating here is AC only.
5) How do I tell if one of these square body fuses has blown without pulling it out?
Each fuse carries a top-mounted status indicator, so a maintenance tech can check condition visually at the holder rather than de-energizing and removing the fuse to test it. Worth noting for panel layout: the indicator sits on top, so leave sightline and clearance above the fuse.
6) Does the Bussmann 170M-415 fuse come with insulated metal gripping lugs?
No, it does not have insulated metal gripping lugs (IMGL). Connection is bolted through the slotted M4 centre-bolted blade tags, so plan on bolted bus or cable lug terminations rather than a gripped, touch-safe front. If your panel requires finger-safe terminations, that has to come from the holder or enclosure.
7) What applications is a 170M Class aR high speed fuse normally specified for?
Semiconductor protection is the job: variable frequency drives, motor control, rectifier and thyristor circuits, and industrial power conversion gear. The high speed element clears a fault faster than the silicon can fail, which is why it shows up in front of diodes and thyristors rather than as general feeder protection.
