Bussmann 170M2690 – Frequently Asked Questions

1) What is a Bussmann 170M2690 aR fuse actually for, and can I use it as a general branch circuit fuse?
The 170M2690 is a high speed square body fuse with utilization category aR, meaning accompanied semiconductor protection. It is built to clear fast enough to protect diodes, SCRs and IGBTs in drives, rectifiers and soft starters. aR is partial range: it handles short circuit current only, so it must be used alongside an overload protective device. It is not a substitute for a general purpose branch circuit fuse.
2) Will the Bussmann 170M2690 fit my existing square body fuse holder?
It is a square body fuse with knife blade contacts, so it mounts to bolted or clamped blade stations rather than a ferrule clip. Overall size is 217 mm long by 85 mm wide by 65 mm high, so check the cabinet depth and phase spacing against those numbers before you commit. It has no insulated metal gripping lugs, so the blades are the bare bolt-down type.
3) How do I tell if a 170M2690 has blown without pulling it out of the panel?
It carries a top fuse status indicator, so a maintenance tech can see an opened fuse from the front of the assembly instead of de-energizing and removing each one. On a three phase drive stack that is the difference between a glance and a full teardown. Some panel builders also use the top indicator pin to drive a microswitch for remote alarm.
4) Is 125 kAIC enough interrupting capacity for my drive panel?
The 170M2690 is rated 125 kAIC, which covers most industrial service entrances and drive cabinets where available fault current is well under that figure. Compare it against the available fault current calculated at the point of installation; the fuse interrupting rating has to equal or exceed it.
5) Is the 10 amp rating on the 170M2690 the motor current or the semiconductor rating?
The fuse is rated 10 A continuous, and on an aR semiconductor fuse that figure is sized to the device it protects, not to the motor nameplate. Size it from the rectifier or IGBT I2t and RMS current data from the drive manufacturer, then match the fuse. Dropping a 10 A aR fuse into a circuit sized for a larger element will cause nuisance opening.
6) What exactly am I ordering when I buy Bussmann 170M2690, and how does it ship?
170M2690 is the genuine Eaton Bussmann manufacturer part number for this 10 A high speed square body aR fuse, sold as a single fuse in standard packaging. Each piece weighs roughly 218 grams. There is one model on the part, so there are no finish or option codes to specify when ordering.
7) Is the 170M2690 an AC or DC fuse?
It is rated for AC service. DC applications on high speed fuses carry separate voltage and time constant limits, so do not apply this one on a DC bus without ratings from the manufacturer for that duty.
