We recommend fuse protection through the use of properly selected I2t fusing (semiconductor fuses). Devices such as circuit breakers and general purpose fuses, while sufficient and necessary for load and installation protection, do not provide adequate protection for the semiconductor device.

Part Numbers

The part number shows the physical size of the fuse (14 mm or 22 mm diameter) and the amperage of the fuse. The FUSE-HLDR fuse holders are finger safe, din rail units.
