General Electric TED124100 U Thermal Magnetic Circuit Breaker

The General Electric TED124100U thermal magnetic circuit breaker serves as a primary overcurrent protection device designed for standard industrial electrical distribution systems where reliable disconnection during fault conditions is essential for safety. This specific two-pole unit features a continuous current rating of 100 amperes and withstands up to 480 volts AC, making it ideal for integration into main feeder circuits feeding heavy machinery or transformer banks in commercial facilities.

Operating through dual-action technology, the internal mechanism employs a thermal-bimetal strip to detect prolonged overload heat and an electromagnetic coil to respond instantly to short-circuit spikes, enabling the breaker to handle various fault currents without manual replacement of components. This design supports maintenance workflows in regulated industrial plants by providing a reusable connection point that resets manually once the external circuit issue is resolved, ensuring system availability remains high during troubleshooting phases.

While designed for industry-standard dimensions, installers must verify physical fitment against specific panelboard bus bars to guarantee secure mechanical attachment and proper torque settings for optimal electrical contact efficiency and longevity.
