FAQs
Install the EPCS2211A by mounting it in a single-gang Pauluhn enclosure and connect conduit through the 1/2" NPT entry. Ensure the enclosure maintains IP66 integrity and the wiring adheres to NEC/CEC standards for hazardous locations. Use proper gaskets and seals to prevent moisture ingress, and verify that the switch is securely fastened to avoid vibration-induced wear. This approach minimizes field adjustments and maximizes long-term reliability.
The EPCS2211A is rated for 20A at 120-277 Vac and features an IP66 enclosure for robust protection in dusty or wet environments. It is certified for hazardous locations under NEC/CEC, with Class I, Division 1 and 2 and Class II, Division 1 and 2 ratings. These specs ensure safe operation in oil, gas, chemical, and other demanding industrial atmospheres while supporting reliable switching performance.
Yes. With IP66 protection and copper-free aluminum construction, the EPCS2211A is well-suited for marine and offshore applications where exposure to salt spray and moisture is a concern. Its hazardous-location ratings and 1/2" NPT entry facilitate compliant installation in Pauluhn enclosures, enabling durable and safe control solutions in challenging environments.
The EPCS2211A carries NEC/CEC standards, Hazardous/Classified Location ratings, and IP66 protection. These certifications indicate compliance with safety and electrical codes for equipment used in hazardous areas, helping meet regulatory requirements, streamline approvals, and reduce compliance-related project risk in industrial facilities.
The copper-free aluminum enclosure and IP66 protection reduce corrosion and environmental wear, extending service life in harsh facilities. The rugged design, plus standard wiring via 1/2" NPT entry and surface-mount installation, minimizes field servicing. As a result, maintenance intervals lengthen and downtime is reduced, delivering lower total cost of ownership over the switch’s operational life.
