Electric vehicle high-voltage DC fuses need to meet different certification standards when exported to different regions, among which IEC and UL are the most common mainstream standards.
There are obvious differences in rated voltage marking, breaking current grade, temperature resistance range and overload protection logic between the two standards. IEC standards are widely used in Europe and Asia, and UL standards are mandatory for North American market access.
High-speed fuses used in new energy vehicle main circuits need to pass strict short-circuit breaking test, temperature cycle test and aging durability test.
EssFuse EV series DC fuses support dual-standard production, meet both IEC and UL test requirements, and can be freely matched with global new energy vehicle circuit design.
