TYPE NON CARTRIDGE FUSE, 250-VOLT, 30-AMP, 2-PK.

The Cooper Bussmann 30 amp Brass Cartridge Fuses are designed as 1-time fuses that are non-current limiting. These class K5 cartridges are intended for use in light-duty, general-purpose circuit applications. These fuses have a 250 volt maximum rating. Protect lighting, heating and other circuits not subject to temporary surges and where available short-circuit currents are relatively lowNon one-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 occurFor general purpose circuits, size at amp rating of circuitFor motor circuits, size at 300 percent to 400 percent according to the nec motor ampacity tables 430.247 to 430.250, per 430.6 (A)(1)250 volts2 per card2" x 9/16"30 amp
