TEYD3020B - 20Amp Circuit Breaker

TEYD3020B - 20Amp Circuit Breaker

When your dependable circuit protection matters, the GE TEYD3020B is built to handle the job. This 20-amp, 3-pole thermal magnetic circuit breaker is made for 480Y/277V class electrical systems and installs with a secure bolt-on connection in compatible panelboards. Whether you're replacing a failed breaker or maintaining an existing distribution system, it offers the protection and consistent performance needed to keep electrical equipment operating safely. The thermal magnetic trip unit reacts to both sustained overloads and short circuits, helping reduce the risk of damage to wiring and connected equipment. A non-interchangeable trip means the factory trip setting remains fixed, giving you confidence that the breaker will perform as intended. With an interrupting capacity of 25kA at 480VAC and 65kA at 240VAC, the TEYD3020B is a practical choice for a wide range of commercial and industrial applications where reliable overcurrent protection is essential.
