GE TEYL3025B - 25 A, 480 V, 3-Pole Bolt-On Circuit Breaker | AmpState

GE TEYL3025B is a 25A, 480V, 3-pole bolt-on molded case circuit breaker engineered for dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. The bolt-on mounting delivers a rigid, vibration-resistant bus connection, so you get consistent performance even in environments with movement or thermal cycling.

At the heart of its reliability is a thermal-magnetic trip unit that provides stable, repeatable protection. The thermal element handles normal overloads with precision, while the magnetic component responds quickly to short circuits, helping protect downstream equipment and reduce downtime.

• Secure bolt-on mounting for a solid, vibration-resistant bus connection that stays put through operating conditions.
• Thermal-magnetic trip unit delivers stable protection with fast magnetic response to short circuits and controlled thermal trips for overloads.
• OEM-compatible design works with matching load centers and panelboards, ensuring a fit that maintains electrical integrity and system timing.
• Versatile applications suitable for residential, commercial, and light industrial environments where 3-phase, 480V distribution is in play.
