Bussmann 170M6019 – Frequently Asked Questions

1) Will the Bussmann 170M6019 fuse fit a DIN 43 620 square body fuse holder?
Yes. The 170M6019 is built to the DIN 43 620 dimensional standard with a square body and slotted center bolted tags, so it drops into standard DIN-style square body mounts. Body size is 168 mm long, 95 mm wide and 76 mm high. It uses a blade end x blade end connection, so your busbar or holder needs bolted blade terminations, not clip-in ferrule ends.
2) Is a Class aR fuse like the 170M6019 the right choice, or do I need a gR/gS type?
Class aR is partial-range protection: it clears short circuits on power semiconductors but does not protect against overloads. That means the 170M6019 has to sit behind, or alongside, a separate overload protective device such as the drive's electronic overload or an upstream breaker. If you want one device covering both overload and short circuit in the same branch, you want a full-range gR or gS semiconductor fuse instead. For drives, rectifiers and converters where the control electronics already handle overload, aR is the normal specification.
3) What voltage and fault current can the Bussmann 170M6019 handle?
It is dual rated at 700V under UL and 690V under IEC, AC only, with a 200 kAIC interrupting rating. That covers typical 480V and 600V industrial drive systems and high fault-current service entrances where available short circuit current is well above what a standard fuse can clear. It is not a DC-rated device on these ratings.
4) What I2t values do I need to coordinate the 170M6019 with my SCRs or diodes?
Use 580,000 A2s pre-arc (melting) I2t and 3,900,000 A2s clearing I2t at 660V. The rule for semiconductor protection is that the fuse total clearing I2t must be less than the I2t withstand of the SCR or diode it protects, so compare 3,900,000 against your device datasheet figure at the relevant fault duration. Watts loss at rated current is 160.
5) Can maintenance tell at a glance whether this 1600A fuse has blown?
Yes, the 170M6019 carries a top-mounted fuse status indicator, so a technician can confirm the fuse condition visually without pulling it from the holder or metering it out. That matters on a 1600A square body fuse, which is bolted in and awkward to remove just to check. Note it does not include insulated metal gripping lugs, so handle it by the body with the circuit isolated.
6) What part number do I order for this Bussmann high speed square body fuse?
Order Bussmann part number 170M6019. It ships in standard packaging, one fuse per unit, and there are no finish, mounting or indicator sub-options to specify on it, the indicator and blade terminations are fixed to that number.
