Littelfuse 10EV and 20EV High-Voltage Automotive Fuses provide a 20kA interrupting rating and 500VDC voltage rating while operating over a -40°C to +125°C temperature range. The Littelfuse 10EV Fuses are cylindrical, low-voltage, high-current devices that employ diffusion pill technology to provide time-delayed protection to circuits in electric vehicles (EVs) and hybrid passenger vehicles. 20EV Fuses are bolt-down fuses that can be installed in most EVs and hybrid passenger vehicles for circuit protection.
