Rockwell Automation: 140ME Motor Protective Switching Devices – Where Motor Protection Meets Smart System Design
July 7, 2026
The 140ME Motor Protective Switching Device delivers more reliable branch‑circuit protection by combining disconnect capability, magnetic short‑circuit protection, electronic overload protection and manual switching for motor control.
Built to safeguard motors from overload, phase loss, and short‑circuit conditions, the 140ME provides dependable protection while maintaining the high electrical performance required for demanding applications.
For manufacturers, the 140ME offers advantages in both performance and ease of use. By consolidating multiple protective and control functions into a single device, it reduces panel complexity and simplifies installation. Operators benefit from clear status indication and predictable trip behavior, making it easier to identify issues, restore operation quickly and maintain consistent uptime. Its compact footprint also helps panel builders optimize space without compromising accessibility or safety.
The 140ME is a key component of Rockwell Automation’s Branch Motor Control & Protection portfolio, working alongside 100‑E Contactors, 140MT Motor Protection Circuit Breakers and E100 Electronic Overload Relays. Together, these devices create a unified motor control architecture that simplifies design, strengthens motor protection and improves coordination across in-panel architectures. This alignment helps deliver consistent performance and a smoother engineering experience from design through commissioning.
With the latest release of the EtherNet/IP In‑cabinet Solution, the 140ME becomes even more powerful. New connectivity through a 100‑E Contactor communication module brings real‑time diagnostics, device health insights and operational data directly onto the EtherNet/IP network. This integration allows manufacturers to monitor motor conditions, identify issues quickly and support predictive maintenance strategies, all while reducing wiring and simplifying panel design. The result is a smarter, more connected motor control ecosystem that scales effortlessly as operational needs evolve.
