FAE Expert Insights
"The FWP series square body fuses are excellent for compact power electronics designs. The FWP-100A at 100A provides great protection for medium-power IGBT modules while the square body format saves space compared to cylindrical fuses. I've used these extensively in servo drives and compact motor drives where space is at a premium. The thermal performance is excellent due to the flat surfaces, and the bolt-on mounting provides reliable connections. I2t values are competitive with larger cylindrical fuses. For applications requiring 100A protection in limited space, this is my recommended solution."
