General Electrics THFK236100WL - 100 A, 3-Pole Circuit Breaker | AmpState

Meet the General Electric THFK236100WL—a 100 A, 3-pole molded case circuit breaker designed to deliver reliable branch circuit overcurrent and short-circuit protection for panelboards and loadcenters. Built to fit seamlessly into GE and compatible OEM systems, this breaker keeps critical electrical infrastructure safe and performing at peak efficiency.

• Compact molded-case design minimizes footprint and saves valuable panel space, helping you fit more circuits without crowding your enclosure.
• Thermal-magnetic trip unit provides stable, repeatable protection by reacting to both sustained overloads (thermal) and high fault currents (magnetic), reducing nuisance trips while ensuring fast disconnection when it matters.
• OEM-compatible integration is designed for use in matching GE loadcenters and panelboards, simplifying replacement and upgrades within established electrical systems.
• Versatile for multiple industries—ideal for residential, commercial, and light industrial applications where dependable 3-pole protection is needed.

The THFK236100WL is purpose-built to guard three-phase circuits and multi-wire branch circuits in panelboards and loadcenters. Its 100 A rating makes it suitable for protecting feeders and distribution paths that handle significant current while keeping wiring within safe limits. The thermal-magnetic mechanism ensures protection performance remains consistent across varying ambient temperatures and load conditions, so electrical systems stay safeguarded without compromising on performance.

Why this breaker matters for your project

• Space-efficient protection lets you design cleaner, more organized panels without sacrificing safety.
• Predictable protection thanks to the thermal-magnetic trip curve helps prevent both nuisance trips and delayed disconnections during faults.
• Simple replacement workflow with OEM-wide compatibility reduces downtime when upgrading or maintaining GE-based panel systems.
• Clear use cases include service entrances, feeders to subpanels, and branch circuits in commercial spaces or light industrial environments where robust overcurrent protection is essential.
