Bussmann 170M3114 – Frequently Asked Questions

1) Can I use a Bussmann 170M3114 aR fuse as the only overcurrent protection on a drive?
No. The 170M3114 is a Class aR fuse, meaning accompanied semiconductor protection. It clears short-circuit and semiconductor fault currents only, so it has to work alongside a separate device (breaker or overload relay) handling overload protection. If you need a fuse that protects across the full range on its own, you want a gR/gS type rather than an aR.
2) What voltage and fault current can the Bussmann 170M3114 handle?
It is rated 690V AC per IEC (700V under UL) with a 200 kAIC interrupting rating, so it suits 690V class industrial power conversion gear on stiff supplies. It is an AC-rated device; do not apply it on a DC bus based on the AC rating.
3) Will the 170M3114 bolt into my existing square body fuse holder?
It is built to the DIN 43 620 mounting standard with a square body and slotted center bolted tags, blade end to blade end. If your existing base or busbar is DIN 43 620 prepped for the same body size, the bolt pattern lines up. It is not a clip-in or ferrule fuse, so it needs bolted terminations.
4) What I2t numbers do I need to coordinate the 170M3114 with my semiconductor?
Pre-arc I2t is 1100 and total clearing I2t is 7500 at 660V, with a clearing loss figure of 30. Compare the clearing I2t against the I2t withstand of your diode, thyristor or IGBT module: the device rating has to exceed 7500 for the fuse to protect it.
5) Does the Bussmann 170M3114 have insulated gripping lugs or a blown fuse indicator for remote monitoring?
No insulated metal gripping lugs on this one, so the tags are bare and need proper clearance and torque at the bolted joint. The indicator type is listed as Other, which means it is not a standard visual striker style, so if you are driving a microswitch for remote alarm, confirm the striker option you need before standardizing.
6) Is the Bussmann 170M3114 acceptable for CE marked export equipment?
Yes. The fuse is IEC rated and CE marked, which is what an OEM shipping power conversion equipment into Europe needs on the bill of material. It also carries a UL voltage rating of 700V for North American builds.
7) How big is the 170M3114 fuse and how much does it weigh for panel layout?
Dimensions are given as 305 mm, 145 mm, and 65 mm, and it weighs about 321 g. Allow for those overall figures plus terminal access when you lay out the fuse base in the enclosure.
