Locking mechanism with key actuator provides security and prevents accidental operation, directly reducing risk of injury and unplanned downtime during maintenance. In control panels, this translates to improved operator accountability and smoother lockout procedures. High current rating of 20A at 120/277 V supports a wide range of industrial loads, including motor control circuits and automation actuators. For panel designers, this means fewer devices to manage and easier compliance with electrical codes. Back and side wiring offers installation flexibility, enabling quicker retrofits and cleaner panel layouts in tight spaces. This configuration supports reliable field connections and simplifies commissioning in crowded or legacy panels. The 14 lbf-in torque rating ensures consistent contact pressure and long-term reliability, while the durable Urea material withstands industrial environments. The three-way switch architecture supports multiple wiring configurations to accommodate evolving automation schemes. Certifications such as cULus Listed and UL Recognized provide regulatory peace of mind and facilitate cross-site deployments. Overall, AH1223L delivers a compact, robust solution that reduces maintenance costs and improves uptime in manufacturing and packaging lines.
