TEYF3090B - 90Amp Circuit Breaker

TEYF3090B - 90Amp Circuit Breaker

The GE TEYF3090B is a 3-pole, 90 amp thermal magnetic circuit breaker built for use in 480Y/277V Class electrical distribution systems. Featuring a bolt-on design, it mounts securely into compatible panelboards while providing reliable protection against overloads and short circuits. Its fixed, non-interchangeable 90 amp trip makes it a good choice for applications where a permanent trip rating is required. With an interrupting capacity of 18kA at 480VAC and 65kA at 240VAC, the TEYF3090B is capable of protecting branch circuits and equipment in many commercial and industrial installations. Whether you're replacing an existing breaker or maintaining an electrical distribution system, this Type TEYF breaker offers the performance and compatibility expected for demanding electrical environments.
