Ferraz Shawmut's D0-Linocur switch-disconnector-fuse, uses sophisticated switching and clamping technology and is designed for maximum safety, ease of use and speed. It comes with a newly developed monitoring device. The D0-Linocur is a compact combination of a D0 fuse-base and a switch-disconnector in one housing with a maximum rated current of 63 A and a rated voltage of up to ~440 V. One of the outstanding safety features is the special screw cap with a clearly visible start and end position. A single 90° rotation suffices to insert or remove the unit. The correct end position of the screw cap is immediately recognizable. The switch is made of extremely heat-resistant materials.
