| Non current limiting |
| Protect lighting, heating and other circuits not subject to temporary surges and where available short circuit currents are relatively low |
| NON 1-time fuses do not have any appreciable degree of time delay and thus should not be specified in circuits where large transients or motor overloads occur |
| Use Bussmann advanced protection Fusetron™ FRN-R or ultimate protection Low-Peak™ LPN-RK dual element, time delay fuses |
| For general purpose circuits, size at amp rating of circuit |
| For motor circuits, size at 300% to 400% according to the NEC motor ampacity tables 430.247 to 430.250 per 430.6(A)(1) |
| 50 kA at 250 VAC RMS sym |
