TEYL2100B - 100Amp Circuit Breaker

TEYL2100B - 100 Amp Circuit Breaker

The TEYL2100B is a 100 Amp, 2-pole thermal magnetic circuit breaker designed for use in your compatible 480Y/277V Class panelboards. Its bolt-on design provides a secure installation, while the non-interchangeable trip helps maintain consistent protection throughout the life of the breaker. With interrupting ratings of 65kA at 480VAC and 100kA at 240VAC, it's well suited for applications where higher available fault current requires a breaker with greater interrupting capacity.

The thermal magnetic trip unit responds to both sustained overloads and short circuits, helping protect electrical equipment and branch circuits from damage. Whether you're replacing an existing breaker during routine maintenance or servicing a commercial or industrial electrical system, the TEYL2100B offers the performance and specifications professionals expect from the TEYL product line.
