FAQs
For CPS732 312, ensure correct through-feed back box installation in a two-gang enclosure and confirm Class I, Division 1/2 compliance per NEC/CEC. Use copper-free aluminum housing and brass contacts to maintain grounding integrity and minimize ignition risk in volatile environments. Verify area classification and follow manufacturer installation instructions to avoid compromising explosion-proof performance.
Delayed action circuit breaking reduces nuisance trips during motor startup and transient overload events, protecting motor windings and connected equipment. This improves uptime in process lines and reduces maintenance cycles, making it suitable for applications with frequent start-stop loads in hazardous locations.
Yes. CPS732 312 is designed for a 1" trade size, two-gang back box with through-feed installation. The two-gang footprint accommodates multiple receptacle connections in a single hazardous-location assembly, simplifying wiring harnessing and reducing enclosure footprint in control panels and junction boxes.
The Arktite CPS assembly carries NEC/CEC standards with Class I, Division 1 and Division 2 ratings and area classification for hazardous environments. This ensures compliance for explosion-protected receptacles in oil, gas, chemical, and other process industries, streamlining regulatory approvals and field audits.
By providing reliable explosion-proof operation, reduced downtime from nuisance trips, and a durable copper-free aluminum housing, CPS732 312 lowers total cost of ownership. Its factory sealing and robust materials minimize preventive maintenance, while broad voltage compatibility reduces SKUs and inventory costs over time.
