Selection Notes
Semiconductor fuses are chosen on I²t let-through against the device surge rating, not on continuous current alone.
Common Questions
How should I select the 170M7636 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.
