General Electrics THFK236225WL - 225 A, 3-Pole Circuit Breaker | AmpState

The General Electrics THFK236225WL is a robust 225 A, 3-pole molded case circuit breaker designed to safeguard panelboards and load centers from overcurrent and short-circuit events. Built for dependable branch circuit protection, this unit integrates seamlessly into GE OEM panels to maintain coordinated protection across your electrical system.

Why this breaker stands out

• Compact molded case design minimizes space impact in your enclosure, helping you fit more circuits and keep wiring tidy without sacrificing protection.
• Thermal-magnetic trip unit delivers stable, repeatable protection: the thermal element responds to sustained overloads, while the magnetic element provides an instantaneous trip during high-energy faults, reducing the risk of damage to downstream equipment.
• Three-pole configuration ensures balanced protection for 3-phase systems, making it ideal for commercial, industrial, and larger residential installations.
• OEM panel compatibility designed to pair with matching GE load centers and panelboards, preserving proper trip curves and system coordination for reliable operation.
• Versatile application suitable for residential, commercial, and light industrial environments where robust feeder protection is crucial.
