Littelfuse JTD400ID Indicator Fuse 400A 600VAC 500VDC 20000A Knife-Blade Slo-Blo

Offering advanced protection for industrial motor applications, the JTD_ID Series by Littelfuse features fused combination motor controllers that provide IEC Type II (no damage) motor branch circuit short-circuit and ground fault protection. Designed to streamline operations and minimize maintenance, these indicator fuses showcase superior performance characteristics, allowing them to serve a wide range of applications while significantly reducing fuse inventory. With their unique indicator window, machine operators can quickly identify a blown fuse at a glance, ensuring reduced downtime and enhanced safety by limiting exposure to live circuits. The JTD_ID indicator fuses not only decrease the likelihood of nuisance openings due to their effective time-delay and cycling characteristics but also minimize the risk of equipment damage through robust overload and short-circuit protection. Ideal for use in motor control centers and transformer protection, these fuses support general purpose circuits, particularly when space is at a premium, making them a reliable choice for diverse industrial environments.
