Description
Part of Eaton's legacy WMZS line, this 40A supplementary protector delivers UL 1077 recognized defense for industrial control circuits. It provides targeted protection where branch circuit breakers are already present. The three-pole unit installs onto standard 35mm DIN rails inside automation panels. It serves as a cross-reference for discontinued WMS series components and transitions to the modern FAZ-C40/3. Featuring a C-curve trip characteristic, it handles moderate inrush currents.Specifications
