Bussmann 170M1369 – Frequently Asked Questions

1) Will the Bussmann 170M1369 fuse fit a standard DIN square body fuse holder?
The 170M1369 is built to DIN 43 620 dimensional standards with a square body and slotted offset bolted tags, so it mounts in holders and disconnects prepped for that standard. Termination is blade end x blade end, which means it bolts down at both tags rather than clipping in. Stated dimensions are 105 mm length/depth, 46 mm height, 300 mm width, and it weighs 135.9 g.
2) Can a Class aR fuse be used as the only overcurrent protection on a drive circuit?
No. Class aR means accompanied semiconductor protection, so the 170M1369 clears short-circuit and high fault current only. It does not protect against overload on its own, so it has to be backed by a separate overload device such as a breaker or motor overload relay in the same circuit. If you need a fuse that handles the full range from overload through short circuit, you want a gR/gS type instead.
3) Is the Bussmann 170M1369 rated for a 600V or 690V AC drive?
Yes on both counts. The 170M1369 carries a 690 V AC rating (IEC), and the description lists 700V under UL, so it covers 480V and 600V class equipment as well as 690V IEC drive systems. It is an AC-rated part.
4) How do I know the let-through energy is low enough to protect my SCRs or IGBTs?
Compare the fuse I2t values against the semiconductor's withstand rating. The 170M1369 has a pre-arc I2t of 2300 and a total clearing I2t of 16000 at 660 V. The device you are protecting has to have an I2t withstand above the clearing figure at your system voltage, otherwise the semiconductor fails before the fuse does.
5) How much heat does the 160A Bussmann high-speed fuse put into the enclosure?
Watt losses are 32 W at rating. Multiply that by the number of fuses in the cabinet when you size ventilation or a panel cooler, and derate per the holder manufacturer's guidance if the enclosure runs hot.
6) Can I tell if the 170M1369 has blown without pulling it out of the holder?
Yes. It has a top-mounted fuse status indicator, so a technician can confirm the condition visually from the front of the panel. There are no insulated metal gripping lugs on this version, so handling still requires the fuse to be de-energized and isolated.
7) What is the exact part number to order for a 160A Bussmann square body semiconductor fuse?
Order Bussmann 170M1369. That is the manufacturer part number for the 160A, 690V AC, Class aR square body high-speed fuse with blade end x blade end tags, and it ships in standard packaging.
8) Does the Bussmann 170M1369 meet IEC and CE requirements for export machinery?
The 170M1369 is IEC rated and CE marked, which is what a machine builder shipping into Europe generally needs to show on the circuit protection.
