Littelfuse CNN100E - CNN_E fuses are rated for applications up to 80 V dc. As fork lift trucks and electrical vehicle system voltages increase, circuit protection needs to be rated higher than the standard CNN products to handle the increased voltage. The CNN_E is considered very fast-acting for quicker reaction time.
