Bussmann 170M1826 – Frequently Asked Questions

1) Can the Bussmann 170M1826 fuse be used on a 1000V DC circuit, or is it an AC-rated fuse?
The 170M1826 is rated 160A at 1000V DC and is built specifically for direct current service, not a re-badged AC fuse. That matters because DC has no current zero crossing, so an AC-rated fuse of the same amperage cannot be assumed to interrupt the same fault on DC. Use it where the circuit is DC at or below 1000V.
2) What does the aR class on the Bussmann 170M1826 mean for protecting my drive or rectifier?
aR is an accompanying semiconductor fuse: it clears short circuits fast enough to save diodes, IGBTs and SCRs, but it is not a full-range device. It passes normal overload current rather than clearing it, so overload protection has to come from something else in the circuit, typically the drive's electronic overload or an upstream breaker. If you need one device to cover both overload and short circuit, an aR fuse is the wrong choice.
3) Will the Bussmann 170M1826 fit my existing fuse holder or bus bar mounting?
The 170M1826 uses the 230FU/90 body and mounting configuration, so it drops into holders and bus bar arrangements prepped for that designation. If your existing fuse carries a different body code, the bolt pattern and centres will not line up and you will need the matching holder or a fuse of the same body style.
4) Is the Bussmann 170M1826 fuse acceptable for a European or CE-marked panel build?
It is manufactured and tested to IEC 60269-4, the standard covering fuses for protecting semiconductor devices, and it is CE compliant. That is the pairing a panel builder needs for a CE-marked assembly. IEC 60269-4 is the certification held on this fuse; it is not a UL-listed device, so a North American listed-equipment job should be specified against a different range.
5) Is a 160A semiconductor fuse like the Bussmann 170M1826 suitable for solar and battery DC applications?
Yes. The 170M1826 is applied in DC power distribution, renewable energy and solar systems, battery backup and DC switchgear, plus VFD and power conversion equipment. The 1000V DC rating is the reason it suits string PV and high-voltage battery systems, where array or pack voltage climbs well above what a typical 600V device covers. Size the 160A rating against the continuous DC current of the string or feeder it protects.
6) What part number should I order to replace a Bussmann 170M1826?
Order it by the Bussmann catalogue number 170M1826. That is the manufacturer part number for the 160A 1000V DC aR square-body fuse, and it is the number to quote so you get the matching 230FU/90 body rather than a same-amperage fuse in a different size or class.
