| Pin-indicating |
| Original fuse providing circuit protection |
| Protect lighting, heating and other circuits not subject to temporary surges and where available short circuit currents are relatively low |
| 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™ LPS-R or ultimate protection Low-Peak™ LPS-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) |
