Applications for Class CC Fuses:

Three types of Class CC dual element fuses, specifically designed to protect different types of components:

Motor protection – CCMR series; dual-element, time-delay fuses specifically designed to protect motor circuits up to 40 HP.
Small transformer protection (control power transformers) – KLDR series, time-delay fuses designed to withstand the high magnetizing inrush of transformers.
General purpose protection of equipment requiring fast overload protection – KLKR series, fast-acting fuses used for protection of equipment containing solid-state devices or other electronic components requiring fast response on overloads.
