Common Questions
What are the ratings of the Eaton Bussmann 170M5929?
1000 V / 630 A, with a 125 kAIC interrupting rating.
How much fault current can the 170M5929 interrupt?
125 kAIC. The available fault current at the installation point must not exceed this value.
What does Class aR mean for the 170M5929?
Class aR defines the fuse's time-current characteristic. E-rated fuses carry a defined melting curve so they coordinate predictably with upstream and downstream devices; mixing E and non-E ratings in one feeder defeats that coordination.
How does the 170M5929 connect?
Flush-end contact. Confirm the mating clip, holder or busbar before ordering — ferrule and blade ends are not interchangeable.
How should I select the 170M5929 for a circuit?
Match the voltage rating to the system voltage, keep the continuous current above the load current, and check that the interrupting rating exceeds the available fault current. In medium voltage work, select on the transformer or feeder fault level rather than the load current alone.
