TEYL3020B - 20Amp Circuit Breaker

TEYL3020B - 20 Amp Circuit Breaker

The TEYL3020B is a 20 amp, 3-pole thermal magnetic circuit breaker with a bolt-on mounting design for use in compatible 480Y/277V Class electrical distribution equipment. It combines overload and short-circuit protection in a single breaker, making it a practical choice for protecting three-phase branch circuits in your commercial and industrial applications. The fixed, non-interchangeable trip provides a consistent protection setting, while the bolt-on construction helps create a secure connection inside the panel. With an interrupting capacity of 65kA at 480VAC and 100kA at 240VAC, the TEYL3020B is built for applications where higher available fault current must be considered. Whether you're replacing an existing breaker or servicing electrical equipment, this model offers the electrical ratings and configuration needed for many demanding installations.
