NITD4 – COOPER BUSSMANN

The NITD4, manufactured by Cooper Bussmann, is a cylindrical fuse cartridge designed for overcurrent protection in AC circuits. It is rated for a maximum current of 4 Amperes (4A) and a maximum voltage of 550 Volts AC (550VAC). This fuse is intended for industrial applications where higher voltage protection is required. Its cylindrical form factor facilitates installation in standard fuse holders designed for this type of cartridge. The NITD4 provides a single element, non-time delay characteristic, meaning it is designed to interrupt fault currents rapidly. It is suitable for protecting equipment against short circuits and overloads, and its 550VAC rating makes it appropriate for three-phase power systems and other high-voltage AC applications. The fuse’s construction and materials are selected to ensure reliable performance and consistent breaking capacity within its specified ratings.
