FAQs
The CPH7934 uses a mechanical cable grip and neoprene bushing to seal cables and resist vibration, with mounting provisions compatible with Arktite receptacles. Its 8.13-inch length and 3.06-inch square footprint support secure, tool-friendly installation in control cabinets or exterior enclosures while meeting NEC/CEC requirements. This reduces commissioning time and simplifies field wiring for technicians working in confined spaces.
Likewise, it is a three-wire, four-pole plug rated 30A/60A, with voltage options of 120-240 Vac or 480 Vac and a three-phase configuration. This enables clean, safe motor connections and straightforward integration with standard drives and starters. The dual-voltage capability helps reduce stocking requirements while maintaining performance across multiple plant sections.
Yes. The copper-free aluminum housing and neoprene sealing provide corrosion resistance and ingress protection against dust, moisture, and washdown environments in challenging industrial settings, while the Arktite line is specifically engineered for hazardous locations with reliable moisture seals and rugged cable management. This reduces field service calls and helps maintain uptime in oil, chemical, and manufacturing facilities.
UL certification for hazardous locations confirms suitability for Class I environments, while NEC/CEC compliance and clearly defined area classifications of Hazardous/Classified Locations support safe, compliant installations. The plug is designed to meet both national and cross-border electrical codes, enabling quick procurement and reducing risk during audits. Certified by UL and CSA as well further strengthens supplier credibility.
The rugged build and vibration-resistant grip reduce failed connections and downtime, lowering maintenance frequency and replacement costs. Its cross-volt compatibility minimizes inventory, while UL/NEC/CEC compliance reduces project delays and speeds commissioning across multi-site operations. Additionally, the plug's long service life and minimal rework lower lifecycle costs, while straightforward compatibility with Arktite receptacles reduces field wiring errors during expansion projects.
