Industrial SA-20 Secondary Surge Arrester 175V AC

The Zeus SA-20 Industrial Secondary Surge Arrester delivers fast-response transient voltage suppression for electrical circuits at a nominal 175 VAC, guarding downstream equipment against lightning-induced and switching surges. As a secondary surge arrester in the Zeus Ditek Series, it is designed for industrial-grade protection with panel or inline installation options for electrical protection. It supports electrical distribution systems, control panels, HVAC, and other industrial equipment, and is installed downstream of primary surge protection devices to shield sensitive electronics and automation equipment from residual surges. Specifications include MPN SA-20, Brand Zeus (Ditek Series), Operating Voltage 175 VAC, and its function is transient voltage suppression and surge protection. Common replacements include Ditek DTK-SA series surge arresters, Eaton secondary surge protection devices, and Siemens low-voltage surge arresters.
