Allen-Bradley 140MT-C3E-C10 Circuit Breaker, 10A, 480V

Engineered by Allen-Bradley for demanding industrial environments, the 140MT-C3E-C10 circuit breaker delivers precise, reliable protection for electrical distribution across manufacturing floors, packaging lines, and machine controls. With a 10 amp rating and up to 480V operating capacity, it safeguards equipment and personnel by interrupting fault currents quickly during overloads or short circuits.

Key benefits that matter in real-world use

• Exact part-number accuracy: 140MT-C3E-C10 is designed to fit 140MT frame panels and compatible enclosures, making replacements straightforward and minimizing downtime.
• Adequate 10 A protection for smaller branch circuits and control circuits within industrial systems, balancing safety with operational continuity.
• High-voltage readiness: rated for up to 480V, suitable for common industrial distribution and machine-control networks.
• Proven Allen-Bradley reliability: backed by a legacy of durability and consistent performance in harsh industrial settings.

Ideal applications

• Industrial electrical service installations and panel boards
• Maintenance and replacement projects in manufacturing environments
• Motor control centers and machine-control circuits that require dependable protection at 480V
• Spare or replacement parts for existing 140MT-based installations

Why this specific breaker stands out

What sets the 140MT-C3E-C10 apart is its targeted compatibility with the 140MT frame family, which translates to a drop-in fit in many existing industrial panels. The 10 A rating provides precise protection for circuits that don’t require high-current interruption, helping to prevent nuisance trips while still guarding against overloads. In environments where equipment reliability and rapid downtime recovery are critical, this breaker offers a dependable balance of protection and practicality.

How to verify compatibility (quick, practical checks)
