TEYL3100B - 100Amp Circuit Breaker

TEYL3100B - 100 Amp Circuit Breaker

The TEYL3100B is a 100 Amp, 3-pole bolt-on thermal magnetic circuit breaker designed to provide dependable overcurrent and short-circuit protection in your commercial and industrial electrical distribution systems. Built for 480Y/277V Class applications, this breaker features a non-interchangeable trip unit that delivers consistent protection while helping you to maintain the integrity of your electrical system. With an interrupting capacity of 65kA at 480VAC and 100kA at 240VAC, the TEYL3100B is well suited for installations where higher fault current ratings are required. Its bolt-on mounting design provides a secure connection that helps you minimize movement and supports long-term reliability in demanding environments. Whether you're replacing an existing breaker during maintenance or completing a new installation, the TEYL3100B offers the performance professionals expect for protecting feeders, branch circuits, and electrical equipment. Its thermal magnetic trip mechanism responds to both prolonged overload conditions and instantaneous short circuits, helping reduce the risk of equipment damage and unnecessary downtime.
