Bussmann 170M6208 – Frequently Asked Questions

1) What is a Class aR fuse like the Bussmann 170M6208 used for, and can it protect a motor branch circuit on its own?
Class aR is a partial-range semiconductor protection fuse. The Bussmann 170M6208 is listed for semiconductor protection with utilization category aR (accompanied semiconductor protection), which means it clears high fault currents ahead of diodes, SCRs and IGBTs but is not intended to act alone for overload protection. It has to be accompanied by another device (an overload relay, electronic drive protection or a breaker) handling low-level overcurrents. If you need a fuse that covers the full range including overload, aR is the wrong category.
2) Will the 170M6208 square body fuse mount in my existing DIN 43 620 fuse base?
Yes. The 170M6208 is a square body fuse built to the DIN 43 620 mounting standard with slotted center bolted tags, blade end to blade end. If your holder or busbar stack is drilled for DIN 43 620 square body blades of the same size, it drops in. Body size is 168 x 95 x 76 mm, so confirm you have that clearance in the cabinet before ordering.
3) What I2t values do I use to coordinate the 170M6208 with my SCR or diode?
Pre-arcing I2t is 14000 and clearing I2t is 95000 at 660 V. Match those against the semiconductor's published I2t withstand: the fuse clearing I2t must stay below the device rating for the fuse to actually protect it. The fuse is rated 500 A continuous.
4) How do I tell if a Bussmann 170M6208 has blown without pulling it out of the stack?
It carries a top-mounted fuse status indicator. The indicator pops on the top face of the square body, so a tech can check state visually from the front of the panel without unbolting the blades. If you want remote signalling instead, you need a microswitch-equipped version rather than a plain top indicator.
5) Is 200 kAIC enough interrupting capacity for a drive at the service entrance?
The 170M6208 is rated 200 kAIC, which covers available fault current on most industrial services and rectifier front ends. Compare that figure against the calculated available fault current at your point of installation; anything at or below 200,000 A symmetrical is within the fuse rating.
6) Does the 170M6208 come with insulated gripping lugs for hot handling?
No. The 170M6208 is supplied without insulated metal gripping lugs (IMGL). It is a bolted blade fuse, so removal means de-energizing and unbolting the tags; there are no insulated grips for pulling it. If your maintenance procedure depends on gripping lugs, specify an IMGL version of the square body instead.
7) Is the Bussmann 170M6208 acceptable for an IEC-built machine shipping into Europe?
It is IEC rated and CE marked, which is what a machine builder needs for documentation on a panel built to IEC practice. It is an AC fuse; the published ratings are for AC service, so a DC link application needs the manufacturer's DC derating data rather than the AC figures.
8) What exactly do I order to get this fuse, and is it a genuine Eaton Bussmann part?
Order by manufacturer part number 170M6208, the Eaton Bussmann series high speed square body fuse, 500 A, Class aR, blade end to blade end, in standard packaging. There is one configuration of this part number, so there are no suffixes or options to specify.
