Description
Overview
The Rockwell Automation 140MT-C3E-B10 Motor Protection Circuit Breaker delivers precision, reliability, and performance in modern motor control systems. Built to safeguard electrical circuits, it ensures consistent protection while reducing unnecessary complexity in installations.
Certified Safety and Standards
Because it’s UL and CSA listed, this breaker meets stringent global safety requirements. Therefore, it can serve as a branch-circuit and short-circuit protector for individual motor circuits. No additional short-circuit protection is needed, except for the feeder conductors, which require upstream safeguarding.
Design and Construction
The breaker features a C-frame design, combining strength, compactness, and durability. With a normal break operation, it guarantees immediate disconnection during electrical faults. This design minimises equipment damage, prevents overheating, and ensures system longevity. Moreover, its rugged structure makes it suitable for both new installations and retrofit applications.
Performance and Functionality
The adjustable thermal and fixed magnetic trip mechanisms allow a precise response to overloads and short circuits. The thermal component reacts to sustained overcurrents, while the magnetic trip acts instantly during high current surges. Consequently, motors remain protected, and downtime stays minimal.
Compatibility and Efficiency
Additionally, this breaker integrates seamlessly with Allen-Bradley motor control systems, ensuring stable coordination and improved operational efficiency. Its compact build saves valuable panel space, while the simplified wiring design accelerates installation and reduces maintenance effort.
