GE THQC2145 - 45 A, 240 V, 2-Pole Circuit Breaker | AmpState

Meet the GE THQC2145, a reliable 45-amp, 240-volt, 2-pole molded case circuit breaker designed to shield your electrical system from overcurrent and short-circuit faults. Built for panelboards and load centers, this breaker delivers focused protection where you need it most—without compromising space or performance. Available through AmpState, it’s a practical upgrade or replacement that keeps wiring safe and systems running smoothly.

• Compact molded-case design: Maximizes panel space and eases installation in tight electrical enclosures, helping you fit more circuits without sacrificing accessibility.
• Thermal-magnetic trip unit: Delivers stable, repeatable protection by combining thermal overload sensing with immediate magnetic trip on high-energy faults, reducing nuisance trips and safeguarding downstream wiring.
• 2-pole, 240V protection: Ensures simultaneous disruption of both conductors on a fault, maintaining system safety and preventing unequal voltages from circulating in 240V circuits.
• OEM compatibility: Designed to align with GE OEM load centers and panelboards, simplifying replacements, upgrades, and inventory management.
• Versatile for multiple environments: Suitable for residential, commercial, and light industrial applications where dependable branch-circuit protection is essential.

Specific use cases include protecting 240V circuits such as HVAC equipment, water heating, and certain large electrical feeds, as well as providing safe, code-compliant protection for lighting runs and small-motor loads in commercial or light industrial settings. With a clear 45A rating, it’s a precise choice for circuits that require robust protection without oversizing your panelboard.
