Quick Summary

EDSC2129 SA snap switch control station delivers robust hazardous-area control for industrial panels. Maintenance teams often battle sealed enclosures that trap heat or leak when seals wear, increasing downtime. This unit meets NEC/CEC standards and provides Class I Division 1 and 2 ratings as well as Class II/III ratings, plus NEMA 3/7/9 enclosure protection for broad hazardous-location coverage. With copper-free aluminum and factory sealing, it’s lighter to install and engineered for long service life in harsh environments, reducing maintenance costs. From reliable through-feed wiring to two 3/4" hubs, it supports 120-277V, 20A circuits, helping you simplify compliance and speed commissioning.
