TEYD2050B - 50Amp Circuit Breaker

TEYD2050B - 50Amp Circuit Breaker

The TEYD2050B is a 2-pole, 50-amp bolt-on thermal-magnetic circuit breaker designed for dependable overcurrent protection in commercial and industrial electrical systems. If you're replacing a worn breaker or servicing an existing panel, this model offers the performance needed to help keep equipment protected and power flowing as expected.

Designed for 480Y/277V Class applications, the TEYD2050B uses a non-interchangeable thermal magnetic trip that responds to both sustained overloads and sudden short circuits. Its bolt-on design provides a secure connection within compatible panelboards, while its interrupting ratings of 25kA at 480VAC and 65kA at 240VAC make it well-suited for demanding electrical environments. From HVAC equipment and lighting circuits to motors and distribution panels, this breaker is a practical choice wherever dependable circuit protection is required.
