FAQs
The 1221W supports back and side wiring with screw terminals and is designed for flush mounting in industrial panels. It accepts #14-10 AWG conductors, enabling flexible installation in tight enclosures while maintaining secure, code-compliant terminations. This combination reduces wiring complexity and helps installers achieve clean, serviceable panel layouts.
The switch is rated for 20A at 120/277 V, suitable for a wide range of industrial loads. The torque rating is 14 lbf-in, which ensures reliable actuation without over-tightening terminals. These specs support stable switching under common industrial duty cycles and reduce contact wear over time.
Ideal for construction-grade industrial panels, OEM equipment, and machinery control enclosures, the 1221W is well-suited to manufacturing, processing, and packaging lines where robust actuation, dependable wiring, and compact front-mount design are essential. Its single-pole configuration simplifies control circuits and is widely compatible with standard industrial wiring practices.
The 1221W carries UL and cULus listing along with NOM certification, signaling compliance with North American safety and performance standards. These certifications reduce regulatory risk, simplify customer approvals, and support safe operation in diverse facilities, including those requiring stringent electrical protection and control components.
With durable polycarbonate housing and brass terminal enclosure, the switch resists environmental wear and maintains reliable contact performance in dirty or humid environments. The back and side wiring plus flush mount simplify field maintenance and replacements, minimizing downtime. Over the component’s life, these features translate to lower maintenance costs and a faster time-to-market for panel upgrades or new builds.
