Bussmann 170M7683 Class aR Semiconductor Fuse, 1700A 1250V AC
The Bussmann 170M7683 is a Class aR semiconductor protection fuse rated 1700A at 1250V AC, purpose-built for accompanied semiconductor protection in demanding power electronics applications. As a Class aR (accompanied semiconductor protection) utilization category device, the 170M7683 is engineered to work alongside a properly coordinated backup overcurrent protective device rather than serve as stand-alone branch-circuit protection. Configured in the compact 4BKN/105 AR body style, this Bussmann fuse delivers the current-limiting performance that semiconductor protection circuits demand from a 1250V AC-rated device.
