Copper-free aluminum housing delivers corrosion resistance and lighter weight, which reduces handling costs and installation time while improving lifespan in harsh environments. This translates to lower total cost of ownership and fewer spare-part requirements on site. The three-wire, four-pole configuration with Style 2 grounding simplifies wiring, minimizes field wiring errors, and enhances fault tolerance for critical equipment such as pumps and fans in hazardous areas. In addition, the mechanical cable grip and neoprene bushing provide dependable strain relief and environmental sealing, reducing ingress and extending connector life in oily or dusty plants. A cable diameter range of 0.875 to 1.375 inches accommodates common field cables, enabling rapid field upgrades without rework or adapters. The comprehensive electrical ratings—7A/30A, 120–240 VAC, and 480 VAC for three-phase systems—support small to medium motor loads up to 1 HP/3 HP, delivering reliable performance across diverse line configurations. Compliance features include NEC/CEC standards and NEC hazardous ratings for Class I Div 1 and Div 2, along with area classification for hazardous/classified locations, ensuring procurement alignment with safety regulations while simplifying audits and inspections. These capabilities combine to reduce downtime, streamline installation, and improve overall plant safety and productivity for industries such as chemical processing, oil and gas, and mining.
