3 Phase Surge Suppressor Unit, 100kA, 480Y/277 V, Flange Mount

HWA Surge Protective Devices

Range of suppressors and noise filters in compact size, this allows surge suppression to be installed adjacent to power panels or directly on sensitive equipment in harsh electrical conditions.
HWA SPDs provide high-quality surge suppression for a wide variety of commercial, industrial or institutional applications, and can be used in a network of surge suppression applications or as a stand-alone surge suppressor

Square D

For use with Qwikline I consumer units and can be retrofitted in to existing systems,Type B characteristic offers instantaneous short circuit response level of 3-5 x normal rated current, making it suitable for circuits with moderate inrush currents such as filament lamps, heating loads and most domestic/small building protection applications.,Type C characteristic offers short circuit response of 5-10 x normal rated current, making it ideal for circuits with higher inrush currents such as motor control and fluorescent lighting installations in industrial buildings where nuisance tripping might occur if a faster type was used
