FAQs
NCS23 installs as a dead-end, 3/4 in trade-size enclosure designed for Class I Division 2. Mounting should follow standard enclosure practices with appropriate seals, gaskets, and proper strain-relief for wiring. Maintain minimum clearance per NEC/CEC guidelines and use compatible conduit fittings to preserve NEMA ratings. Ensure wiring conforms to the 3-circuit configuration and dead-end design for optimal performance.
NCS23 supports 3 circuits in a 3/4 inch trade-size dead-end enclosure, with dimensions of 11.75 inches in height, 4.38 inches in width, and 3.81 inches in depth, weighing 2.35 pounds. It carries NEC/CEC compliance and a Class I Division 2 hazardous location rating, with NEMA protection ratings of 3, 4X, 7, and 12 for versatile industrial use.
Yes. The NCS23 enclosure is designed to meet NEC/CEC standards and a Class I, Division 2 hazardous location rating, along with NEMA ratings 3, 4X, 7, 12. This combination ensures regulatory compliance and robust protection for automation panels operating in hazardous environments.
NCS23 is ideal for hazardous-location control panels in chemical processing, oil and gas facilities, and other industrial settings requiring Class I Division 2 protection. Its compact form factor and 3/4 in trade-size capability suit small to medium control circuits, while its NEMA ratings support rugged, outdoor or corrosive environments.
The NCS23 delivers improved uptime by reducing exposure risk in hazardous locations and simplifying maintenance through its compact, durable design. Regular inspections of seals and gaskets, plus compliance with NEC/CEC requirements, lower compliance risk and potential downtime costs.
