Description
KLDR fuses are time-delay fuses designed to protect control
transformers, solenoids and similar inductive components
with high magnetizing currents during the first half-cycle.
They provide excellent protection of motor branch circuits
containing IEC or NEMA rated motor controllers or
contactors.

Features/Benefits
• Meets UL and CSA standards
• Class CC fuses are the smallest 600 V, 200,000 A.I.R.
fuses approved for branch circuit protection
• Rejection feature prevents use of fuses with lower
interrupting ratings or voltage ratings when used with
corresponding fuse holders
• Extremely current limiting reduces damage caused by
heating and magnetic effects of short-circuit currents
