FAQs

Install the DSD SR30223 using standard panel mounting compatible with EDS/EFS back boxes. Ensure proper enclosure sealing, secure mounting with the two-pole design, and verify conductors are rated for 600 Vac. Follow NEC/CEC guidelines for Class I Division 1 environments and confirm connections are electrically isolated to maintain safe operation.
The DSD SR30223 provides a 30A amperage rating, 600 Vac voltage rating, and supports a two-pole, two-position configuration. It operates as a double-throw without OFF with electrically isolated contacts, and is compatible with EDS/EFS back boxes for hazardous-location installations, enabling reliable motor control up to 10 hp.
Yes. The selector switch is designed for hazardous/classified locations with NEC/CEC compliance and Class I Division 1 capability. It also carries compatible NEMA ratings (3, 5, 12), making it suitable for a broad range of industrial control panels in challenging facilities.
The device is designed for use with EDS/EFS back boxes, simplifying integration into existing hazardous-location enclosures and new builds. This compatibility reduces retrofit effort and speeds up commissioning in Class I Division 1 installations.
Copper-free aluminum construction reduces weight and corrosion-related maintenance, while isolated contacts minimize mis-wiring risk and unintended energization. The robust housing and back-box compatibility support longer service life, lower replacement costs, and faster technician servicing, delivering tangible lifecycle cost savings in hazardous-area automation.
