Cartridge and Axial Lead Fuses Class CC* Fuses > CCMR, KLDR and KLKR Series Class CC fuses CCMR, KLDR and KLKR Series Description Fast-Acting KLKR fuses provide fast-acting protection to equipment containing surge sensitive components. Use KLKR Fuses for non-inductive loads not requiring time- delay. CCMR fuses (formerly KLMR) are specically designed to withstand sustained starting currents of small motors. The CCMR Fuses provide short-circuit protection for motor branch-circuits. KLDR fuses are specically designed to withstand the momentary high magnetizing currents of control transformers, solenoids, and similar inductive loads.
