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 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.
