TEYF3100B - 100Amp Circuit Breaker

TEYF3100B - 100 Amp Circuit Breaker

The TEYF3100B is a 100 Amp, 3-pole bolt-on circuit breaker used in 480Y/277VAC electrical distribution systems. It uses a thermal magnetic trip mechanism to protect connected equipment from overloads and short circuits, helping reduce the risk of damage when abnormal electrical conditions occur. This model has a non-interchangeable trip, so the trip rating stays fixed after installation. Its bolt-on mounting also provides a secure connection in compatible panelboards, making it a common choice for commercial and industrial applications where a dependable breaker is needed. The TEYF3100B carries an interrupting rating of 18kA at 480VAC and 65kA at 240VAC, making it suitable for many three-phase power distribution systems. Whether you're replacing an existing breaker or matching the specifications of an installed panel, the TEYF3100B offers the electrical ratings needed for a wide range of equipment, including feeders, lighting panels, HVAC systems, and other branch circuits.
