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
