BUSSMANN 63NZ02
The BUSSMANN 63NZ02 is a low-voltage D0-size fuse designed to protect cables and equipment against overload and short circuits. It is a time-delay fuse, allowing it to withstand short inrush currents without blowing unnecessarily. Furthermore, it is rated for 63 A at 400 V AC, making it relevant for many fixed installations as well as control and distribution environments.
The fuse is specified in application category gL/gG, which is used for general cable and equipment protection. Its compact D02 size makes it easy to fit into appropriate fuse holders where standardized and predictable protection is required.
In practice, a fuse like this is chosen when a simple and robust disconnection function is needed in the system. The high breaking capacity of 50 kA means that it is suitable for installations where high fault currents may occur and where the fuse must be able to disconnect safely.
