FAQs
To install the EPCS2211B, mount the switch in a compatible Pauluhn EPCS-style enclosure with a single-gang face. Use the 1/2 in NPT entry for conduit connection, ensure proper sealing to maintain IP66 integrity, and verify Class I/II hazardous-location ratings are appropriate for your area. Wire the line and load per NEC/CEC guidelines and perform a functional test before commissioning. The unit’s surface-mount design aids in clean, rapid installation, reducing field modifications and potential ingress paths.
The EPCS2211B is rated for 20A and operates on 120–277 VAC, making it suitable for common control circuits in hazardous locations. This rating supports reliable switching of motor starters, pumps, and other actuators within explosion-protected environments, while maintaining compatibility with standard control wiring practices and protective device coordination.
Yes. The unit carries NEC/CEC approvals for Hazardous/Classified Locations, including Class I, Division 1 and 2 and Class II, Division 1 and 2. This makes it suitable for chemical plants, refineries, mining, and marine applications where corrosive atmospheres and potential ignition sources exist, ensuring safe switching in compliance-driven installations.
The EPCS2211B features NEC/CEC compliance and hazardous-location ratings (Class I and II, Division 1 and 2) along with IP66 ingress protection. These certifications confirm suitability for harsh environments, water and dust resistance, and adherence to widely adopted electrical standards, reducing certificate-related project delays.
Adopting the EPCS2211B reduces maintenance visits by delivering durable brass construction and robust sealing that resist corrosion and ingress. Its straightforward installation and compatibility with Pauluhn EPCS enclosures lower field labor costs and downtime. The switch’s compliance with hazardous-location standards helps avoid rework or retrofits later, improving overall lifecycle value and uptime for critical processes.
