FAQs
Yes. The CPH7913 is specified for a two-wire, three-pole configuration in single-phase systems, making it compatible with typical motor starters and controllers used in hazardous locations. It supports 0.5 to 1.5 HP motors and accepts cables within the 0.875 to 1.375 inch diameter range, enabling straightforward field wiring and reliable connections under vibration and dust. Proper torque and sealing procedures should be followed to maintain enclosure integrity.
The CPH7913 carries NEC/CEC compliance with Hazardous/Classified Locations ratings and NEC hazardous ratings for Class I, Division 1 and Division 2. These certifications verify suitability for explosive atmospheres and ensure conformance to recognized safety standards. When specifying for a project, reference these ratings to satisfy regulatory and customer requirements, and maintain proper documentation for audits and inspections.
The plug is designed for cable diameters from 0.875 to 1.375 inches, supporting common field cables used in motor and control circuits. For mounting, ensure a secure mechanical grip and proper neoprene bushing seating to maintain environmental seal. Verify compatibility with single-phase feeds and confirm that the conduit or gland entries remain sealed to preserve explosion-proof integrity in hazardous locations.
Copper-free aluminum housing offers corrosion resistance and lighter weight without sacrificing mechanical strength, which is advantageous in corrosive environments like chemical plants or offshore facilities. The Style 2 grounding arrangement provides reliable earth continuity, while the material choice helps reduce weight on overhead or rotor-mounted assemblies, improving handling and installation time while maintaining符合 safety and regulatory expectations.
The Arktite CPH7913 plug reduces maintenance through robust sealing (neoprene bushing and mechanical cable grip) that minimizes ingress of dust and moisture, lowering cleaning and replacement needs. Its rugged build, combined with NEC/CEC compliance, streamlines maintenance planning, reduces unplanned downtime, and supports longer service life for motors and control systems in hazardous locations, yielding a favorable total cost of ownership over time.
