TEYH3050B - 50Amp Circuit Breaker Description
TEYH3050B - 50 Amp Circuit Breaker
The TEYH3050B is a 50 Amp, 3-pole thermal magnetic circuit breaker built for protecting three-phase electrical systems from overloads and short circuits. Its bolt-on design provides a secure fit in compatible panelboards, while the non-interchangeable trip unit keeps the breaker at its factory-rated trip setting for consistent performance over time. Designed for 480Y/277V Class applications, the TEYH3050B carries an interrupting rating of 35kA at 480VAC and 65kA at 240VAC, making it a dependable choice for commercial and industrial electrical distribution systems where higher available fault current may be present. Whether you're replacing an existing breaker or maintaining electrical equipment, this model delivers the protection expected from a thermal magnetic molded case circuit breaker.
