3-158-852

3-158-852 is an EKO81 series high-performance HV fuse designed for industrial and energy applications. This square-body fuse provides safety and reliability, while its robust construction enables it to withstand mechanical vibration, shock, chemical exposure, and extreme temperatures ranging from -40 °C to +125 °C. Its ceramic housing and tin-plated copper alloy terminals ensure durability and stable electrical performance, even under harsh operating conditions. The fuse is suitable for a wide range of applications, including charging infrastructure, manual service disconnectors, energy storage systems (BESS), including packs, racks, PCS, sections, modules, and PDUs, as well as power conversion devices such as UPS systems, inverters, rectifiers, and drives. It is also suitable for industrial equipment, including heaters, welding equipment, metalworking equipment, and other industrial machinery.
