Bussmann 170M5468 – Frequently Asked Questions

1) Can I use the Bussmann 170M5468 as a general branch circuit or motor fuse?
No. The 170M5468 is a high-speed semiconductor fuse-link with an aR utilization category, meaning accompanied semiconductor protection. aR fuses only protect against short circuits and rely on another device (a breaker or overload relay) for overload protection. It is intended for DC common bus, DC drive, and reduced voltage starter applications, not as a standalone branch circuit or motor overload device.
2) Will the Bussmann 170M5468 fit my existing square body fuse holder?
It is a Size 2 square body fuse-link with flush end contacts, so it bolts to flat busbar pads or a Size 2 square body base rather than clipping in. Body dimensions are 77 mm length/depth, 59 mm height, and 51 mm width. It does not have insulated metal gripping lugs, so if your holder requires an IMGL version you need a different part. Match the mounting center distance on your existing base before ordering.
3) Is the 1250A Bussmann 170M5468 rated for DC circuits?
The published rating is 1250 A at 600 V AC. The voltage type on this fuse-link is AC only. It is commonly applied to protect DC common bus and DC drive equipment, but that refers to the equipment being protected, not a published DC voltage rating. If you need a stated DC voltage rating for your circuit, specify a fuse published with a DC rating.
4) How much heat does a 1250A Bussmann high-speed fuse put into the enclosure?
Rated power dissipation is 130 W per fuse-link. On a three-phase drive with three of these installed, that's roughly 390 W of heat inside the cabinet, which matters when you size enclosure ventilation or a cabinet cooler. Derating also applies if the fuse sits in still air at elevated ambient.
5) Is the Bussmann 170M5468 UL Listed or UL Recognized, and is it RoHS compliant?
UL Recognized, not UL Listed, and it is also designed to IEC standards. UL Recognized means it is a component evaluated for use inside larger listed equipment such as a drive or starter panel, which is exactly how these semiconductor fuses get applied. The fuse-link is RoHS compliant.
6) Does the Bussmann 170M5468 have a blown fuse indicator for a microswitch?
It is built with a single indicator, which gives a visual show of fuse condition. Whether a striker-operated microswitch can be added depends on the indicator style, and this one is catalogued with a non-standard indicator type rather than a striker pin, so don't assume a microswitch kit mounts to it.
