Eaton Specification Sheet - EPCS2212B
Feature → Business Impact → Application: The EPCS2212B provides a 20A, 120-277 Vac two-pole switch with 1/2 in NPT entry and brass enclosure. This combination supports heavy-duty control in hazardous environments, reducing the need for external relays and simplifying wiring. In a wastewater treatment plant or chemical processing line, it enables reliable isolation and quick servicing without recurring downtime. IP66 enclosure protects against dust and water ingress, delivering lower maintenance costs and longer mean time between failures; ideal for outdoor enclosures, mining conveyors, and offshore equipment. The 1/2 in NPT entry facilitates straightforward conduit connections, speeding field installation and retrofit projects while reducing enclosure modification. Brass construction affords long-term durability in corrosive environments, supporting minimal maintenance cycles in chemical plants and refineries. NEC/CEC compliance plus hazard ratings (Class I/II Div 1/2) provide regulatory confidence for safe operation in regulatory-sensitive facilities. The single-gang, dead-end design saves panel space and simplifies wiring schematics, enabling faster commissioning on crowded control boards and retrofit projects. In practice, these attributes translate to lower total cost of ownership through reduced parts, fewer field service visits, and improved system reliability.

FAQs
The EPCS2212B is designed for surface-mount, single-gang installations with a 1/2 inch NPT entry. Its brass enclosure and compact footprint streamline panel layouts, while the IP66 rating and two-pole 20A, 120-277 Vac capability ensure reliable operation in Class I/II hazardous areas. This combination reduces the need for additional enclosures or relays and simplifies wiring during retrofit projects.
Key ratings include 20A amperage and 120-277 Vac voltage, with a two-pole configuration and an enclosure rated IP66. It is intended for hazardous/classified locations (Class I/II, Divisions 1 and 2). The device is a snap switch with a switch included, suitable for demanding industrial control applications while meeting NEC/CEC standards.
Yes. The IP66 enclosure rating provides robust dust-tight and water-resistance protection, making it suitable for outdoor installations, damp facilities, and harsh industrial settings. Its brass construction further enhances durability in challenging environments such as chemical plants, oil and gas sites, and offshore equipment, reducing maintenance frequency.
The 1/2" NPT entry standardizes conduit connections, simplifying field wiring and reducing installation time. This feature supports streamlined gland/wiring arrangements for both new builds and retrofits, enabling quicker commissioning and easier future upgrades without rework.
The EPCS2212B meets NEC/CEC standards and hazardous-location ratings for Class I/II Div 1/2, alongside IP66 ingress protection. These certifications facilitate regulatory compliance, reduce risk during audits, and help justify lifecycle cost savings through fewer field modifications, lower downtime, and improved reliability in critical process environments.
