Strikesorb surge protection device

The Strikesorb surge protection device (SPD) provides continuous protection from over-voltage and other transient voltage activity for industrial equipment, such as variable-speed drives (VSDs), programmable logic controllers (PLCs) and power cabinets. Available in a wide variety of voltage and packaging configurations, SPD modules protect equipment from lightning strikes, power surges and spikes without performance deterioration. The modules meet IEC 61643-1 and UL 1449 (2nd edition) requirements. Their unique fuseless design, along with their ability to withstand high short-circuit currents, allows direct installation on bus-bars and eliminates the need to install additional fuses or interconnection wires. Strikesorb modules are comprised of a single, large distribution-grade metal oxide varistor (MOV) disc in an environmentally sealed aluminum housing that provides uniform distribution of the surge current over the total area of the MOV protection element. This results in a high energy-handling capability with ultra-low let-through voltage to the industrial equipment. The monolithic design provides a straight electrical path directly to the suppression element, providing extremely low contact resistance and superior heat dissipation to prevent aging and premature failure.
