KLDR time delay fuses are 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.

Cole Hersee® Time Delay Fuse, Series: KLDR Series, Non-Indicating, Rejection, 600 VAC/300 VDC, 1.5 A, Class CC, 200 kA, 20 kA Interrupt Rating, 12 s Response, Dual Element, Cylindrical Body, Ferrule Terminal, Holder Mounting, Melamine Body, 1-1/2 in Length, 0.405 in Diameter

• KLDR fuses are time delay fuses specifically designed for the protection of control transformers, solenoids and similar inductive components with high magnetizing currents during the first half cycle
• They closely match most control power transformer characteristics, which permits the time delay fuses to be sized in accordance with the latest revisions of UL 508 (industrial control) and UL 845 (motor control centers)
• When the time delay of KLDR fuses is adequate to carry motor starting current, they provide excellent protection of motor branch circuits containing IEC or NEMA rated motor controllers or contractors
• Compared to other UL Listed fuses, Class CC time delay fuses are the most current limiting, rating for rating
• Time delay fuses provide this superior protection in a fraction of the space required by other fuse classes
• Reliable interruption of all over currents up to 200000 A
• Extremely current limiting - reduces damage caused by heating and magnetic effects of short circuit currents, stops damaging short circuit faster than any mechanical protective device
• Class CC time delay fuses are the smallest 600 V, 200000 A.I.R. fuses approved for branch circuit protection
