- Holder voltage and current ratings must meet or exceed the fuse they carry — an undersized holder becomes the weak point in the circuit.
Common Questions
What are the ratings of the Eaton Bussmann B221-30FGFST?
120/240 V / 30A, with a 10 kAIC interrupting rating.
How much fault current can the B221-30FGFST interrupt?
10 kAIC. The available fault current at the installation point must not exceed this value.
How should I select the B221-30FGFST 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.
