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.
