They come in smaller sizes. I have a switch box that contains one of these fuses, but it's much smaller. I need this at 40 AMP. I can't tell from the photo if it's true or not. This one has a C33 in the back. My little 30 amp says W51. You make a small 40 amp fuse. The switch box is designed for up to 60 amps.
