GE THQL21100 - 100 A, 240 V, 2-Pole Plug-In Circuit Breaker | AmpState

GE THQL21100 is a 100A, 240V, 2-pole plug-in molded case circuit breaker engineered to protect your panelboard and load center circuits with precision and reliability. Designed for quick installation and straightforward replacements, this breaker helps minimize downtime during panel maintenance while delivering dependable protection for today’s homes and light-commercial spaces. What makes the GE THQL21100 stand out - Fast plug-in connection translates to easier installations and quicker service calls. Slide it into the panel bus, secure the connection, and you’re ready to restore protection without the fuss of rewiring. - Thermal-magnetic trip unit offers stable, repeatable protection across varying temperatures. The thermal element handles gradual overloads, while the magnetic mechanism responds rapidly to short circuits, helping to prevent damage to wiring and connected equipment. - Molded case design with plug-in mounting combines rugged durability with a compact footprint, making it well-suited for crowded panels and retrofit projects. - OEM compatibility and a guaranteed fit with matching GE load centers and panelboards ensure reliable electrical performance and a clean, code-compliant installation. Ideal use cases - Residential panel upgrades and service panel replacements where a reliable 2-pole, 100A breaker is required for 240V branch circuits. - Light commercial applications such as small offices, retail spaces, and service areas that demand quick replacement and sustained protection for 240V equipment. - Retrofit projects in existing GE panelboards and load centers where reducing downtime and ensuring proper fit are top priorities. Why this matters for your electrical protection - By combining a thermal element with magnetic instantaneous tripping, the GE THQL21100 delivers protection that’s responsive to both prolonged overloads and sudden faults. This helps prevent insulation damage, minimizes nuisance trips, and safeguards downstream devices like motors, HVAC systems, and high-draw appliances. - The two-pole design ensures coordinated protection for paired 240V circuits, maintaining consistent protection across both conductors and improving overall panel reliability. - Plug-in compatibility means technicians can carry a standard spare and perform rapid exchanges in the field, keeping critical loads online with minimal interruption.
