Description
The Littelfuse KLDR.400TXP delivers dependable overcurrent protection for demanding industrial and commercial electrical applications. Rated at 0.4 amps and 600 volts, this time-delay Class CC fuse is purpose-built to safeguard control transformers, solenoids, and inductive loads that experience high inrush currents at startup. Its current-limiting, rejection-style construction prevents nuisance openings during temporary surges while ensuring fast, decisive response to genuine overloads and short-circuit events. The compact Class CC form factor simplifies installation in compatible fuse holders and switchgear, making it an ideal choice where panel space is at a premium. RoHS compliant construction supports environmentally responsible procurement and manufacturing standards.
