FAQs
To install the N2S1121U in hazardous locations, begin by confirming the enclosure IP66/NEMA ratings and Hazardous Location classifications (Class I, Zone 1/2 or Division 2). Mount the device in a compliant enclosure, wire the two circuits through the 1/2 inch trade opening, and follow NEC/CEC guidelines for wiring methods and torque specs. Use the included installation instructions (IF 703) and the Eaton installation sheets to ensure proper sealing, grounding, and labeling. This approach minimizes ingress risk while delivering reliable actuation and safe operation across demanding environments.
The N2S1121U meets NEC/CEC standards for general electrical safety and is rated for Hazardous/Classified Locations (Class I, Zone 1; Class I, Zone 2; Division 2; and Class II, Division 2). It carries IP66 ingress protection and supports NEMA ratings 3, 4X, 7, and 12. UL certifications for the related N2SU/N2SCU non-metallic control stations further corroborate compliance. This combination provides robust regulatory alignment for global installations.
This device is well-suited for hazardous process environments such as chemical plants, oil and gas facilities, mining operations, and offshore platforms. The two-position, two-circuit configuration supports simple start/stop control and remote signaling within fault-tolerant control schemes. Its IP66/NEMA 4X enclosure and 600 VAC rating make it a reliable choice for safety-critical control points where enclosure protection and regulatory compliance are paramount.
The N2S1121U offers installation advantages through its 1/2 inch trade size and non-metallic high-impact polyester enclosure, which reduces weight and corrosion risk while simplifying wiring and mounting. It is compatible with the N2SU/N2SCU family, enabling straightforward retrofits or expansions. The device’s rugged construction supports longer service intervals and predictable maintenance costs, translating to lower total cost of ownership for facilities facing harsh operating conditions.
By combining a rugged IP66/NEMA-rated enclosure with NEC/CEC compliance and a simple two-position, two-circuit design, the N2S1121U minimizes field rework, reduces maintenance cycles, and lowers the risk of unplanned downtime. Its lightweight, non-metallic housing simplifies installation and transport, while its 600 VAC rating supports efficient motor-control integration—leading to faster project commissioning and improved overall equipment effectiveness.
