General Electric TJJ436400 Circuit Breaker

General Electric's TJJ436400 is a three-pole circuit breaker rated for 400 A at 600 V, offering 22 kA interrupting capacity for rapid fault isolation in demanding electrical systems. The device includes a shunt trip for remote disconnection and two auxiliary contacts, enabling external control signals and status feedback essential for coordinated protection schemes in industrial power distribution and for integration with building management or control systems. Designed for integration in switchgear and distribution panels, the TJJ436400 provides reliable overcurrent protection while supporting control wiring that interfaces with building management systems, remote alarms, or other supervisory-control interfaces. This GE breaker offers a robust option for high-current, high-voltage protection that blends local isolation with remote operation and signaling in a single package, making it suitable for demanding industrial power architectures. Part number TJJ436400 identifies a GE breaker in the TJJ family, designed to meet standard protective requirements in industrial and commercial power systems.
