BUSSMANN FWP-200 Fuse

FWP-200 is Eaton Bussmann’s 200 A high-speed fuse in the FWP series, a fast-acting cartridge fuse designed to protect power-electronic loads. It is rated for up to 700 VAC and 700 VDC, with a short-circuit interrupting capacity of up to 200 kA RMS at AC and 50 kA at DC, enabling swift fault clearance in drives, inverters, and other high-current power electronics. This non-indicating fuse is intended for installations where a simple protection device is sufficient, and it is commonly used with Bussmann holders in inverter stages, motor drives, DC-DC converters, and power-supply rail protection. The FWP-200 is built to withstand the transient conditions of switching electronics while maintaining system uptime, providing a 200 A rating that protects heavy-load semiconductor portions without unnecessary nuisance blowing during brief overloads and fault events. The FWP family is a staple choice for high-speed protection in industrial equipment, balancing fast response with robust interrupting performance across AC and DC circuits.
