FAQs
For proper installation, plan for back and side wiring using #14-10 AWG conductors and ensure the panel cutout accommodates the device footprint (1.31 in depth, 3.28 in height, 1.34 in width). Apply the recommended 14 lbf-in torque to terminations and use the key actuator to guarantee maintained closure. Verify clean, tight connections to prevent heat buildup and ensure reliable operation in high-cycle environments.
The AH1193N is rated for 20A at 120/277V, suitable for common industrial loads. It supports back and side wiring with #14-10 AWG conductors, and the 14 lbf-in torque ensures secure terminations. The maintained closure and three-way configuration enable versatile wiring schemes while reducing misoperation and improving control reliability in machinery circuits.
The AH1193N is designed for industrial applications with cULus Listing and RoHS compliance, supporting safety and environmental standards. While not explicitly rated for IP ingress in the provided data, its Corbin-type locking offers robust actuation and vandal resistance within standard panel enclosures. For harsher environments, pair it with appropriate enclosure protection and verify local environmental ratings.
This switch carries cULus Listing for safety and RoHS compliance, with NAFTA alignment. These certifications simplify procurement and regulatory clearance in North American facilities, support sustainability goals, and help ensure electrical safety in installed panels. When planning compliance documentation, reference catalog AH1193N and include the cULus and RoHS statements to meet typical corporate and customer governance requirements.
Investing in the AH1193N reduces downtime from accidental actuation due to its maintained closure and secure key actuator. The robust construction, standard wire size, and straightforward installation shorten commissioning time, lower replacement costs, and ease audits. Over mid- to large-scale deployments, these factors translate to lower total cost of ownership and improved equipment uptime.
