TEYD2020B - 20Amp Circuit Breaker

TEYD2020B - 20 Amp Circuit Breaker

The TEYD2020B is a 20 amp, 2-pole bolt-on circuit breaker designed for dependable overcurrent protection in commercial and industrial electrical systems. Built for 480Y/277V Class applications, it combines thermal and magnetic trip protection to respond to both overload conditions and short circuits. The bolt-on mounting style provides a secure connection to compatible panelboards, while the fixed, non-interchangeable trip helps ensure the breaker continues to operate at its intended protection level.

With an interrupting rating of 25kA at 480VAC and 65kA at 240VAC, this breaker is well suited for facilities where reliable circuit protection is a priority. Whether you're replacing an existing unit during maintenance or completing a new installation, the TEYD2020B is designed to deliver consistent performance in demanding electrical environments.
