The HCHVT500-315B-43E from Hiitio New Energy is a Fast-Acting Square Body Fuse Link. It has a voltage rating of 500 V and a current rating of 315 A. This EV fuse has a breaking capacity of 50 kA and a power loss of 55 W. It has a higher voltage rating, which improves system efficiency by allowing smaller, lower-cost conductors while supporting higher-voltage operation. This EV fuse provides up to ten times faster opening under high fault current conditions and assures reliable protection of circuits and components. It allows greater ampacity within sizing guidelines, excellent power of resisting voltaic impingement, environmental temperature tolerance and excellent resistance to mechanical vibration and impact resistance. This EV fuse is available as a module that measures 108.5 x 58 x 43 mm and is ideal for electrical energy storage, battery pack protection, and backup protection for DC relay.
