General Electrics TFK236125WL - 125 A, 3-Pole Circuit Breaker | AmpState

The General Electrics TFK236125WL is a 125A, 3-pole molded case circuit breaker engineered for dependable branch-circuit overcurrent and short-circuit protection in panelboards and load centers. Designed to fit seamlessly with matching OEM gear, this unit is a practical, long-lasting solution for residential, commercial, and light industrial electrical systems.

• Compact molded case design: maximizes panel space and simplifies installation in tight electrical panels, making it ideal for retrofit projects or compact service enclosures.
• Thermal-magnetic trip unit: combines thermal overload protection with instantaneous magnetic trip, delivering stable, repeatable protection across temperature changes and fast response to short circuits.
• 3-pole configuration: suitable for three‑phase circuits and multi‑wire systems, ensuring coordinated protection across all conductors.
• OEM-compatible: engineered to align with General Electrics load centers and panelboards for reliable fit, consistent trip curves, and straightforward commissioning.
• Versatile protection: ideal as a main or feeder breaker in panels, service entrances, subpanels, or light industrial installations where robust overcurrent defense is required.
