GE TEYL3125B - 125 A, 480 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Meet the GE TEYL3125B — a 125A, 480V, 3-pole bolt-on molded case circuit breaker engineered for dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. Designed for real-world electrical demands, it delivers consistent performance across residential, commercial, and light industrial environments.

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection that stays solid through equipment start-ups and high-load cycles.
• Thermal-magnetic trip unit combines precise thermal sensing with fast magnetic response to deliver stable, repeatable protection when overcurrent or a short circuit occurs.
• Three-pole design matched to three-phase systems, rated at 125A and 480V, to reliably protect feeders and branch circuits in commercial and industrial applications.
• OEM compatibility engineered to work with matching GE OEM loadcenters and panelboards, facilitating straightforward retrofits and replacements.
• Versatile application suitable for residential, commercial, and light industrial installations where robust protection and durable construction are essential.

The GE TEYL3125B stands out where reliability and fit matter most. Its bolt-on style delivers a sturdier connection in environments with vibration or motion, reducing loosening risks that can compromise protection. The thermal-magnetic trip mechanism ensures protection remains precise and predictable across varying temperatures and electrical loads, helping prevent nuisance tripping while still shutting down quickly on genuine faults.

Typical use cases include protecting feeders and branch circuits in mid- to large-scale panelboards, safeguarding HVAC equipment, lighting and power distribution in commercial spaces, and supporting distribution in light industrial settings that run on 480V three-phase systems. If you’re upgrading or stocking a GE-compatible panel, the TEYL3125B provides a dependable, plug-compatible option that keeps existing systems running smoothly.

Ideal for electrical specialists, facilities managers, and contractors who need a durable, high-ampacity breaker that plugs into established GE panel ecosystems. With the GE TEYL3125B, you get a proven, easy-to-specify solution that aligns with GE’s molded-case breaker lineup and delivers reliable protection when every amp counts.
