FAQs
The AH520C5W uses back-wire terminations designed for #12–10 AWG conductors and a cord diameter of 0.433–0.84 inches. Start by aligning the four-pole, grounding-ready plug with the mating receptacle, then insert the conductors into the back-wire terminals, tighten to the specified torque, and secure the assembly to the panel. Ensure the enclosure maintains IP69K/IP67 integrity by using compatible seals and gaskets. This approach minimizes wiring errors and reduces installation time while maintaining a robust, vibration-resistant connection.
Verify the amperage rating of 20A and the voltage rating of 347/600V to match your motor or controller. Confirm compatibility with #12–10 AWG conductors and the cord diameter range of 0.433–0.84 inches. The four-pole configuration with grounding supports three-phase motors up to about 7.5 HP, with a 10 lbf-inch torque rating on the terminal interface to ensure secure mating in high-vibration environments.
Yes. The connector features IP69K and IP67 environmental protection and a nylon housing with nickel-plated brass contacts, which resist washdown chemicals and corrosion. These characteristics make it well-suited for challenging environmental conditions found in food & beverage processing lines and wastewater treatment facilities, delivering reliable power connections with reduced maintenance demands.
AH520C5W carries cRUus certification, indicating compliance with North American safety standards. Its IP69K/IP67 ratings provide ingress protection for washdown and dusty environments, and the design supports industrial-grade, three-phase power connections with grounding. When selecting for regulated facilities, these certifications help satisfy essential safety and reliability requirements.
The IP69K/IP67 sealing reduces ingress-related failures, lowering maintenance frequency in harsh environments. The back-wire design and nylon body enable faster field wiring and longer service life, which translates to reduced labor costs per installation and fewer unscheduled outages. Over time, this translates into lower total cost of ownership for motor feeders in demanding industries such as food & beverage and wastewater treatment.
