General Electric TEYF290 Thermal Magnetic Circuit Breaker

General Electric TEYF290 is a two-pole, thermal-magnetic circuit breaker from GE's TEYF family. It is rated 90 A at 480 V, delivering overcurrent protection for a two-conductor circuit. The device combines a thermal element for overload protection with a magnetic element for rapid interruption during short-circuit events, helping prevent overheating and equipment damage in 480-volt electrical installations. The two-pole design ensures both conductors are opened together, which is essential for safe interruption in high-voltage distributions. TEYF290 is suitable for commercial and industrial electrical distributions that require reliable 90-amp protection on 480 V circuits. As a GE TEYF-series device, it reflects the standard construction and performance characteristics used in protecting 480-volt feeders and branch circuits within appropriate electrical systems.
