The CYF4 is a fuse terminal block designed for reliable circuit protection in a wide range of industrial and automation applications. It accommodates standard 5x20mm glass fuses and features a fully enclosed housing, eliminating the need for an additional end plate and providing a neat, space-saving installation. Suitable for both AC and DC circuits, the CYF4 includes a 2-row jumpering provision for flexible power distribution and simplified circuit expansion. Sharing the same profile as the CY4 feedthrough and CYK4 knife disconnect terminal blocks, it can be seamlessly integrated into a DIN-rail layout for a streamlined and organized panel design.
