Bussmann 170M-413 Class aR High-Speed Square Body Semiconductor Fuse, 100kAIC

The Bussmann 170M-413 is an Eaton Bussmann series high-speed square body fuse built for accompanied semiconductor protection, Class aR, to the DIN 43620 standard. This AC-rated fuse delivers an interrupt rating up to 100 kAIC, with clearing I²t values of 125,000 A²s at 1000V and 165,000 A²s at 1250V for demanding power electronics circuits. Its square body features slotted, center-bolted tags for secure busbar-style mounting plus a top-mounted fuse status indicator for fast visual condition checks. It belongs to a Bussmann family spanning 160A to 550A (160A, 200A, 250A, 315A, 350A, 400A, 450A, and 550A) and carries CE marking for compliance in industrial power distribution applications.

Bussmann 170M4138 – Frequently Asked Questions

1) Can I use a Class aR semiconductor fuse as the branch circuit protection for a motor or feeder?
No. Class aR is accompanied semiconductor protection, meaning it only clears short circuits and must work alongside a separate overcurrent device that handles overload. The 170M-413 protects diodes, SCRs and IGBTs in drives, rectifiers and converters. If you need full-range overload plus short circuit protection, you want a gR/gS type or a conventional branch circuit fuse instead.
2) What amp ratings does the Bussmann 170M-413 fuse come in, and what part number do I order?
Ten ratings from 160A up to 630A: 160A (170M4138), 200A (170M4139), 250A (170M4140), 315A (170M4141), 350A (170M4142), 400A (170M4143), 450A (170M4144), 500A (170M4245), 550A (170M4146) and 630A (170M4197). Body dimensions are the same across the group, so the amp rating is the only thing you specify.
3) What voltage and fault current is the Bussmann 170M-413 rated for?
1250V AC, with an interrupt rating up to 100 kAIC. It is an AC-rated part, so do not apply it on a DC bus without a DC rating for the part. Clearing I2t is 125,000 A2s at 1000V and 165,000 A2s at 1250V, which is the number you match against the surge withstand of the semiconductor you are protecting.
4) How do I tell if one of these drive fuses has blown without pulling it out?
There's a fuse status indicator on top of the body, so a maintenance tech can check condition visually with the enclosure open, no meter and no disassembly. On a three-fuse drive input that saves pulling all three tags to find the one that opened.
5) Will a Bussmann 170M-413 fuse pass CE for a machine going to Europe?
The 170M-413 is CE marked and built to the DIN 43620 dimensional standard, which is what a European panel builder or OEM exporting into the EU needs on the semiconductor protection.
6) Does the Bussmann 170M-413 have insulated metal gripping lugs for hot-swap handling?
No, the 170M-413 is supplied without insulated metal gripping lugs (IMGL). The tags are bare slotted center-bolted terminals for bolting to busbar. De-energize and verify the circuit before removing it.
7) How much heat does the 170M-413 fuse put into my enclosure?
Typical power loss is 70W per fuse. Multiply that by the number of fuses in the cabinet when you size ventilation or air conditioning for the panel, since three of them on a drive input is over 200W of added load.
