Littelfuse JTD.800ID Indicator Fuse Slo-Blo Time Delay 0.8A 600VAC 20000A@300VDC Industrial Cartridge

The JTD.800ID from Littelfuse is an advanced indicator fuse that excels in enhancing safety and reducing inventory needs across various applications. Its innovative design provides reliable protection for UL Listed series-rated molded case circuit breaker panels, making it ideal for general purpose circuits including mains, feeders, and branch circuits, especially where space is constrained. What sets this fuse apart is its ability to minimize exposure to live circuits. Once the indicator window darkens, it remains that way regardless of whether power is on or off, ensuring that personnel are safe from potential hazards. With superior time-delay characteristics, it reduces nuisance tripping while also delivering exceptional overload and short-circuit protection, safeguarding equipment from damage. The efficiency of the JTD.800ID allows for quick identification of blown fuses, allowing machine operators to promptly alert maintenance without the need for testing, thereby significantly decreasing downtime.
