General Electric TJF432400 3-Phase Circuit Breaker

General Electric TJF432400 is a 3-pole circuit breaker rated for 400 A at 240 V. It is used to protect three-phase electrical circuits by interrupting fault currents to prevent damage to wiring and connected equipment. The TJF432400 model designation indicates a three-pole configuration with a 400 ampere rating, intended for installation in industrial or commercial distribution panels operating on 240 VAC. In normal operation, it carries the load of a three-phase system up to its rated current and trips when a fault or overload occurs, providing a defined disconnect point for safety and troubleshooting. This device is suitable for applications such as motor circuits, processing lines, and other equipment that rely on 240 V three-phase power and require reliable circuit protection. As a General Electric product, the TJF432400 aligns with standard practices for three-phase distribution components, helping technicians quickly identify its rating and configuration on panels and in documentation.
