Basic protection 250V NON Class K5 and H
general purpose, non-current-limiting, one-time
fuses.
- Protect lighting, heating and other circuits
not subject to temporary surges and where
available short-circuit currents are relatively low
- NON one-time fuses do not have any
appreciable degree of timedelay and thus
should not be specified in circuits where
large transients or motor overloads occur.
Use Bussmann series 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)
