Description
RT18L Series Cylindrical Fuse Holders are designed for installing and securing cylindrical fuse links in low-voltage electrical distribution and protection systems. They provide a stable mounting structure for compatible cartridge fuses and allow convenient installation, removal and replacement during electrical maintenance.
The RT18L series includes two models: RT18L-63 and RT18L-125. These models accommodate different cylindrical fuse link sizes, including 14×51mm and 22×58mm, with rated current options of 63A and 125A respectively.
With a rated voltage of 500/690V, RT18L fuse holders are suitable for electrical installations requiring larger cylindrical fuse configurations. Their compact modular structure supports integration into electrical distribution panels and industrial control assemblies.
The dimensional design includes TH35 DIN rail mounting, providing a practical installation arrangement for compatible electrical enclosures and distribution equipment.
