Feature 30A Amperage Rating and 600 Vac Voltage rating establish the switch as a high-load, safe control point for demanding industrial circuits. Business Impact The robust electrical specification minimizes arcing and wear under load, reducing maintenance cycles and extending service life in harsh environments. Application Suitable for chemical processing, mining, and oil-gas facilities where explosion-protected operation is essential. Feature Three-pole, two-position, double-throw without OFF with electrically isolated contacts provides precise control states without accidental de-energization. Business Impact This configuration enhances operator safety and system reliability, enabling clearer control logic and safer lockout/tagout procedures. Application Ideal for hazardous-location motor control and process sequencing in explosion-prone areas. Feature EDS/EFS back box compatibility simplifies installation and panel integration. Business Impact Faster commissioning and straightforward upgrades cut project timelines and labor costs. Application Works with Eaton back boxes in hazardous locations, supporting standardized mounting and readily available spare parts. Feature NEMA Ratings of 3, 5, 12 and NEC/CEC compliance give broad environmental protection. Business Impact Compliance assurance reduces regulatory risk and accelerates approval cycles for industrial facilities. Application Suitable for outdoor enclosures and harsh indoor environments where dust, water, and chemical exposure occur. Feature Compact depth and measured footprint (2.38 in depth, 5.875 in height, 3.5 in width) simplify enclosure fitment. Business Impact Streamlined installation and retrofit compatibility improve site efficiency and reduce modification costs. Application Seamlessly integrates into existing control enclosures without extensive remodeling.

FAQs

Installation requires mounting the selector switch in an appropriate explosion-protected enclosure and wiring it to EDS/EFS back boxes. Verify the enclosure is rated for the hazardous location class and ensure proper strain relief and seating of conductors. Use the correct torque on terminals and follow lockout/tagout procedures to ensure safe operation during commissioning.
DSD SR30323 is designed for hazardous locations with NEC/CEC compliance and is rated for Class I Division 1 (as well as Class II Division 1 and Class III as applicable). Its electrically isolated contacts reduce arcing, and the explosion-proof construction protects the device from ignition sources, making it suitable for demanding industrial applications.
The switch is rated for 30 A and 600 Vac, configured as a three-pole, two-position, double-throw without OFF with electrically isolated contacts. It is designed for safe actuation and reliable isolation in high-load process control, particularly in hazardous areas aligned with NEC/CEC requirements.
Yes, the DSD SR30323 is used with EDS/EFS back boxes, which simplifies mounting in hazardous-location panels. This compatibility streamlines wiring, reduces enclosure footprint, and accelerates certified installations by leveraging standard back box interfaces and rated seals for explosion-protected environments.
