Littelfuse JTD004ID Indicator Fuse 4A 600VAC 300VDC 20000A Interrupting Rating Slo-Blo

The JTD_ID Series from Littelfuse is engineered to provide enhanced transformer protection, ensuring reliable performance for your electrical systems. With a remarkable interrupting rating of 20,000A at 300VDC, these indicator fuses excel in applications requiring robust short circuit and overload defense. A standout feature is the unique indicator window, which remains dark once the fuse has opened, improving safety and allowing for easy identification of blown fuses without the need for power to be on, thus reducing the risk of accidents. These fuses are designed for general purpose circuits, making them ideal for use in mains, feeders, and branch circuits, especially where space is limited. By combining superior performance with time-delay capabilities, they help reduce nuisance openings and can minimize the required inventory of fuses by serving multiple applications. Whether for motor control centers or fused combination motor controllers, the JTD_ID series ensures that you have reliable and efficient protection tailored to a wide range of industrial needs.
