General Electric TEYD2020B Molded Case Circuit Breaker

General Electric TEYD2020B is a two‑pole molded‑case circuit breaker designed to protect 20‑amp branch circuits in 480Y/277‑V electrical distributions found in commercial and industrial panelboards. As part of GE’s TEY family, the TEYD2020B is specified for use on 480Y/277 VAC systems and provides a robust 25 kA short‑circuit interrupting rating at that voltage, enabling safe interruption of fault currents in typical distribution feeders. The two‑pole construction ensures simultaneous disconnection of both hot legs in a shared enclosure, helping maintain electrical balance in 3‑phase, 4‑wire networks. This TEY series device is intended for panelboard installations where compact, reliable overcurrent protection is required for 480/277‑V services, such as lighting panels, central power distribution, and motor feeders in commercial buildings and light industrial facilities. With its GE pedigree, TEYD2020B is one option in the GE TEY family that supports safe, code‑compliant protection in higher‑voltage electrical systems.
