Cooper Bussmann KAC500 Semiconductor Fuse

Cooper Bussmann KAC-500 Tron Rectifier Fuse is a fast-acting semiconductor fuse rated for 500 A and 600 V AC, designed to protect high-current rectifier circuits and power electronics. The device is part of Bussmann's KAC series and offers a high-speed, non-indicating protection solution for semiconductor power supplies, with an interrupting rating of 200 kA symmetrical (200 kAIC). It is specified for 600 V systems and is commonly used in rectifier banks and other power-electronic topologies where rapid fault isolation is required. The KAC-500 is listed for UL 248-13 and CE approvals and is typically packaged as 1 fuse per carton. This model is one of several KAC fuses in the North American style high-speed family, designed to provide fast response to faults in high-current semiconductor installations.
