Electric vehicle power fuses — 500 Vdc, 350-1000 A
Catalog symbols:• EV40-(amp) 38.1 mm diameter • EV50-(amp) 50.8 mm diameter • EV60-(amp) 63.5 mm diameter
Description:Eaton's Bussmann@ series Electric Vehicle (EV) fuses for the protection of high power battery charging and management systems up to 500 Vdc in ratings from 350 to 1000 amps.
Specifications:Ratings
• Volts - 500 Vdc • Amps - 350-1000A • Interrupting rating • Max DC - 50 kA • Min DC 200% |
Packaging：
Features:• Higher voltage rating provides overall system efficiency using smaller, more economical conductors while meeting the needs of higher voltage battery packs • Higher interrupting rating protects high capacity battery packs needed for vehicle acceleration and range requirements • Up to ten times faster opening under high fault current conditions helps assure reliable protection of circuits and components • Requires up to 48% less space than conventional high speed fuses to help reduce space and weight • Data logging system marks each fuse with a serial number and date code for traceability of Critical to Quality characteristics • To help project the life of the fuse in your application, unique driving profiles and conditions can be simulated to verify proper fuse size and performance under a wide range of driving behaviors • Operation as low as 200% overload provides back up protection to the battery management system • Can be applied in parallel to realize greater ampacity within sizing guidelines |
