Bussmann 170E9713 – Frequently Asked Questions

1) Will a Bussmann 170E9713 fuse work on a 2400V drive circuit?
The 170E9713 is rated 3000 V, so it covers circuits operating at or below that, including a 2400 V drive bus. It carries a 375 A current rating. Voltage rating is a ceiling, not a target, so applying it at 2400 V is within rating, but the current rating still has to suit the circuit.
2) What does Class aR mean on this Bussmann square body fuse, and can I use it as the only overcurrent device?
aR stands for accompanied semiconductor protection. The 170E9713 is built to clear fast on short circuits to protect diodes, thyristors and IGBTs, and it expects another device (a breaker or a gR/gS type fuse) to handle overload and cable protection. Use it as the semiconductor branch protection in a coordinated scheme, not as the sole overcurrent device for a feeder.
3) How does the 170E9713 mount, and do I need bolts or clips?
It is a square body fuse with slotted, center-bolted tags, so it bolts directly to busbar or to a bolt-down fuse base. Slotted tags let you drop it onto studs already in place rather than fully removing them. Bolting hardware is not part of the fuse itself, so plan on the base or busbar hardware your panel uses.
4) Can maintenance tell if this fuse has blown without pulling it out?
Yes. The 170E9713 has a top-mounted fuse status indicator, so a technician can confirm a blown element visually during inspection without a meter and without unbolting the fuse. Mount it with the top face visible and accessible when you lay out the enclosure.
5) Is a high-speed aR fuse the right choice for protecting a rectifier bridge, or should I use a standard industrial fuse?
For a rectifier or inverter bridge, the high-speed aR type is what the semiconductors need. Power diodes and thyristors have very low I2t withstand, and a general purpose industrial fuse clears too slowly to keep the device inside it. The 170E9713 is a 375 A, 3000 V aR fuse intended for exactly that duty: converters, drive front ends, and rectifier and inverter circuits. Keep a separate device for overload and cable protection.
6) What part number do I order for this fuse, and how does it ship?
Order it as Bussmann (Eaton) 170E9713. It ships in standard packaging as a single fuse, not a multi-pack, so order one per fuse position you are protecting.
