Description
Built for industrial OEM panels, the WMS3B08 offers targeted B-curve protection for circuits requiring rapid response to low-level short circuits. This three-pole, 8-amp device snaps onto standard DIN rails, providing UL 1077 supplementary protection where branch circuit breakers are already present. It features finger-safe box lug terminals and a visual trip indicator, acting as a reliable substitute for the newer WMZS3B08 or FAZ-B8/3-NA models.Specifications
