General Electric TC4040TTHE1CR Circuit Breaker

General Electric TC4040TTHE1CR is a 3-pole circuit breaker rated for 4000 amperes, designed to provide high-current overcurrent protection in three-phase electrical systems, and it utilizes the TT40LSH trip unit for its protective operation. The part number TC4040TTHE1CR identifies the exact configuration and specification for this device, confirming its role as a robust protective device with a TT40LSH trip unit as part of its safety mechanism. With a 3-pole architecture, this breaker interrupts all three conductors in a three-phase circuit simultaneously, helping maintain phase balance and prevent damage to downstream equipment during fault or overload conditions. The TT40LSH trip unit denotes the integrated protection logic and response characteristics used by this model to detect abnormal current levels and trigger disconnection in accordance with its design parameters. This GE component is intended for applications requiring reliable, high-current interruption and coordinated protection across multiple phases, making it a critical element in protecting power distribution feeders and heavy-duty electrical loads.
