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 timedelay. CCMR fuses (formerly KLMR) are specifically designed to withstand sustained starting currents of small motors. The CCMR Fuses provide short-circuit protection for motor branch-circuits. KLDR fuses are specifically designed to withstand the momentary high magnetizing currents of control transformers, solenoids, and similar inductive loads.
