Littelfuse offers three different series of Class CC dual-element fuses that are specifically designed to protect different types of components. The CCMR time-delay fuses offer superior protection of motor circuits up to 40 hp. The KLDR time-delay fuses are designed to withstand the high magnetizing in-rush of transformers. The KLKR fast-acting fuses are used for protection of equipment containing solid-state devices or other components requiring fast response on overloads. The CCMR series features POWR-PRO® technology with high-interrupting capability up to 300 kA (self-certified).
