The BUSSMANN FWP-300A is a high-speed, stud-mount semiconductor fuse from Bussmann (now Eaton Bussmann) rated for 300 A and designed to protect high-current power‑electronics circuits. It is a very fast-acting, non-indicating fuse rated for 700 VAC and 700 VDC, with interrupting ratings of 200 kAIC at AC and 50 kAIC at DC. The FWP-300A is built in the North American style with stud-end connections and carries UL Recognized, CSA, and CE markings, making it suitable for use wherever rapid fault interruption is required in power‑electronic assemblies. As part of the FWP family, this device provides robust protection for semiconductor devices and power rectifier paths in demanding environments.
