FAQs
When integrating the EZ1221BK, ensure the panel cut-out accommodates the 1.91 in length, 1.75 in width, and 4.4 in height footprint. Use proper single-pole wiring with a three-wire configuration and verify compatibility with the EZLink modular devices. Follow standard torque recommendations for the mounting screws and maintain proper insulation clearances to avoid arcing or heat buildup in high-load applications.
The 20A, 120-277 VAC rating enables reliable switching of typical lighting loads and several low to medium horsepower motors in industrial panels. This rating supports standard commercial and industrial circuits, reduces the need for overspecification, and helps maintain safe operating temperatures under normal duty. For high inrush loads, consider matching with appropriate circuit protection and wiring gauge per code.
Yes. The EZ1221BK is cULus Listed, NOM certified, and aligned with Federal Specification W-C-596G, ensuring acceptance in regulated environments and broad compatibility with safety and quality requirements. This combination simplifies procurement, reduces qualification testing, and supports compliance during audits in industries such as manufacturing and facilities management.
EZLink modular devices offer a compact, scalable platform that simplifies wiring topology and module-to-module integration. For panel designers, this reduces wiring density, shortens installation time, and enhances maintainability. The EZ1221BK’s single-pole configuration fits many common control schemes, and its modular approach supports future expansions without reworking existing wiring.
The EZ1221BK delivers lower lifecycle costs through durable, maintenance-friendly operation and reduced downtime thanks to reliable 20A performance and robust certifications. Its modular design minimizes retraining and rework during upgrades, while the compact footprint saves panel space and reduces material waste. Over time, this translates to shorter maintenance windows and predictable budgeting.
