They provide ex cel lent protection of motor branch circuits con tain ing IEC or NEMA rated motor con trol lers 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 ## **Applications** - Transformer Protection ## **Web Resources** For additional informations, visit: **littelfuse.com/kldr** ## **Recommended Fuse Holders** **Voltage Rating** AC: 600 V DC: 300 V **Amperage Rating** 1/10 – 30 A **Interrupting Rating** AC: 200 kA rms symmetrical DC: 20 kA **Material** Body: Melamine Caps: Nickel-plated Bronze **Fuse Weight** .019 lb (8.62g) **Approvals** AC: Standard 248-4, Class CC UL Listed[1] /10-30 A (File: E81895) CSA Certified[1] /10-30 A (File: LR29862) DC: Littelfuse self-certified **Environmental** RoHS Compliant **Country of Origin** Mexico ## **Ordering Information** |1/10
