FAQs

The DSD SR30232 is designed to be used with EDS/EFS back boxes, ensuring a secure, code-compliant enclosure for hazardous locations. It supports standard mounting patterns common to Eaton selector switches, enabling straightforward retrofit or new-build installs. Verify enclosure rating and box size to ensure proper fit and clearance for wiring and operator access.
This selector switch is rated for 30A at 600 VAC, configured as a two-pole device with three positions. It features a double-throw with off function, allowing safe disengagement and clear state indication. These specs support reliable control of motors and circuits in hazardous environments while maintaining compatibility with standard control panel designs.
Yes. The DSD SR30232 carries NEC hazardous-location ratings including Class I, Division 1, Class II, Division 1, and Class III, making it appropriate for hazardous locations where flammable gases, vapors, or combustible dust may be present. Always confirm installation per local codes and ensure the enclosure and back boxes meet required IP/NEMA protections.
Key certifications include NEC/CEC standards and a hazardous-location rating for Class I/II/III, Division 1. NEMA ratings 3, 5, and 12 indicate enclosure protection against dust, water, and corrosion. These certifications help streamline regulatory approvals, support safe operation, and facilitate system certification across regional markets.
Maintenance benefits come from robust explosionproof construction and reliable 30A/600 VAC performance, reducing unplanned downtime. The device’s compatibility with common back boxes and its durable enclosure rating minimize corrosion and ingress, extending service life. As a result, operators can anticipate lower maintenance costs and faster mean time to repair (MTTR) in hazardous locations.
