These small-sized fuses provide excellent protection of motor branch circuits containing IEC or NEMA-rated motor controllers or contactors. The KLDR Series fuses closely match most control power transformer characteristics, which permits them to be sized in accordance with the latest revisions of UL 508 (Industrial Control) and UL 845 (Motor Control Centers). ## **Features & Benefits** |FEATURES|BENEFITS| |---|---| |**Current-limiting**|Reduces damage caused by heating and magnetic effects of short-
circuit currents| |**Short-circuit protection**|Improves safety with faster response times to fault currents| |**Rejection capability**|Prevents use of fuses with lower interrupting ratings or voltage when
used with corresponding fuse holders| |**Time-delay**|Allows for a temporary current surge for a short period of time
without blowing| ## **Applications** - Transformer and solenoid protection ## **Specifications** **Voltage Rating** Ac: 600 V Dc: 300 V **Amperage Range** 1⁄10 – 30 A **Interrupting Ratings** Ac: 200,000 A rms symmetrical Dc: 20,000 A self-certified **Material** Body: Melamine Caps: Nickel-plated Bronze **Fuse Weight** .019 lb (8.62g) **Applicable Standards** UL 248-4, Class CC **Environmental** RoHS Compliant **Country of Origin** Mexico **Littelfuse.com/KLDR** ©2022 Littelfuse, Inc.
