Low-Voltage Zinc Oxide Surge Arrester HY 15W-05/26

Overvoltage protection for low-voltage installations: the HY 15W-05/26 diverts switching and lightning-induced surges away from switchgear, transformer windings and control equipment before they reach insulation. Metal-oxide element: the zinc oxide varistor block has the non-linear characteristic that makes an arrester self-restoring after each operation, with no gap to wear or re-seal. Silicone rubber housing: the one-piece silicone rubber shed provides the creepage distance and the contamination performance needed in outdoor substation and industrial environments. Compact and directly mountable: the small envelope suits switchgear cubicles, ring main units and pole-mounted transformer installations where space is limited. Model options: supplied as the HY 15W-05/26 type, with the HY15W-028-13 type available for lower nominal voltages. Application: switchgear, transformer substations, and low-voltage distribution equipment protection.
