GE THQP140 - 40 A, 120 V, 1-Pole Plug-In Circuit Breaker | AmpState

The GE THQP140 is a 40A, 120V, 1-pole plug-in molded case circuit breaker designed to deliver reliable branch circuit protection for panelboards and load centers. Sold under AmpState as a genuine GE device, it combines fast installation with dependable protection, making it a smart choice for both upgrades and new installations in a variety of settings.

• Effortless plug-in installation — Fast, tool-free connection that reduces downtime when adding or replacing breakers in existing panelboards and load centers.
• Thermal-magnetic trip unit — Delivers stable, repeatable protection by responding to both sustained overcurrents and instantaneous short circuits, helping prevent damage to wiring and connected equipment.
• 1-pole, 40A, 120V configuration — Ideal for protecting individual branches in residential, commercial, and light industrial circuits where single-leg protection is required.
• OEM compatibility — Engineered to work with matching GE and OEM load centers and panelboards, ensuring seamless integration and reliable performance.
• Versatile applications — Suitable for a wide range of residential panels, small business electrical rooms, and retrofit projects that demand quick, safe overcurrent and short-circuit protection.

Why choose the THQP140 over generic alternatives? Its precision thermal-magnetic mechanism provides predictable trip behavior, reducing nuisance trips while still delivering prompt protection when faults occur. The plug-in design simplifies serviceability, so when a panel upgrade or routine maintenance is needed, you can swap breakers quickly without rewiring or complex mounting.

Key specifications at a glance — 40A amperage, 120V voltage, 1 pole, plug-in mounting, molded case construction, and intended for branch circuit overcurrent and short-circuit protection. Each THQP140 unit is built to meet demanding electrical standards, helping keep circuits safe from overloads in everyday environments.

Practical tips for best results — verify panelboard compatibility with your OEM brand before installation, ensure the plug-in connection is fully seated, and follow manufacturer torque recommendations for any field-installed components. For ongoing reliability, pair this breaker with properly rated conductors and protective devices in the same electrical system, and use it in panels designed to accommodate GE THQP-series breakers.
