The compact 5.06 in by 5.91 in footprint aids panel integration and simplifies conduit routing.
This unit is designed for NEC/CEC compliance and hazardous locations, with Class I Division 1&2, Class II Division 1&2, and Class III ratings, plus NEMA 7/9/3 compatibility. It is documented for UL certification in hazardous locations, and the installation documents cover IF notices and specification sheets to support compliance audits.
Yes. The EDS21100SA is specified for 1 hp, two-pole operation, with a dead-end style and a 3/4 inch hub. This makes it suitable for small motor applications such as pumps, fans, or conveyors in hazardous environments while meeting regulatory requirements.
Copper-free aluminum provides improved corrosion resistance, lighter weight, and better thermal performance in harsh environments. This reduces maintenance intervals, minimizes galvanic corrosion with fasteners and wiring, and enhances long-term reliability in explosion-protected motor control stations.
The unit is a single-gang enclosure with dimensions 5.06 in wide and 5.91 in high, 3.5 in depth, and includes one 3/4" hub. This footprint supports straightforward wiring and integration into standard control panels, with guided installation documentation to help match it to existing Eaton Crouse-Hinds EDS components.
