Allen-Bradley 140G-R-TLC63 Circuit Breaker

The Allen-Bradley 140G-R-TLC63 (140G-R-TLC63) is a heavy-duty industrial circuit breaker designed for electrical protection, system isolation, and power distribution in automated facilities and machinery. Built under the Allen-Bradley Bulletin 140G product family, this unit provides critical circuit interruption and equipment defense against electrical overloads and short-circuit faults within industrial control panels, switchgear assemblies, and motor control centers. It serves as a direct component for maintenance, repair, and operational overhaul across demanding production environments, ensuring reliable line protection and minimizing costly downtime. With a substantial net weight of approximately 10 kg, the 140G-R-TLC63 features a rugged industrial housing constructed to endure mechanical stress, vibration, and thermal demands typical of heavy industrial switchboards and control cabinets. The device facilitates secure integration into established power architectures, accommodating standard mounting configurations and terminal connections within compatible Allen-Bradley electrical distribution systems. Industrial technicians and panel builders utilize this unit to restore circuit integrity, maintain personnel safety, and protect downstream electrical loads including motors, drives, transformers, and branch circuits. Proper verification of existing catalog numbers and system specifications ensures compatibility during replacement or system expansion.
