General Electrics THQL2140ST1 - 40 A, 2-Pole Plug-In Circuit Breaker | AmpState

The General Electric THQL2140ST1 is a 40A, 2-pole, plug-in molded case circuit breaker designed to deliver reliable branch circuit protection in panelboards and load centers. Its fast plug-in connection simplifies installations and replacements, reducing panel downtime and service calls.

What sets this GE breaker apart is its thermal-magnetic trip unit, which provides stable, repeatable protection against both overloads and short circuits. The thermal element handles steady overcurrent, while the magnetic element kicks in for fast response to high fault currents, helping protect wiring, devices, and connected equipment.

• Plug-in mounting for rapid installation and easy field replacement, with secure, vibration-resistant connections.
• 40A, 2-pole configuration ensures simultaneous disconnection of both poles, ideal for 240V circuits and multi-wire branch circuits.
• Designed for compatibility with matching GE OEM load centers and panelboards, ensuring proper fit, electrical characteristics, and reliable performance.
• Versatile applications suitable for residential, commercial, and light industrial electrical systems needing dependable overcurrent and short-circuit protection.

The THQL2140ST1 is purpose-built for protecting branch circuits from overcurrent and shorts. Install it to safeguard feeders, outlets, motors, and other connected loads in GE panelboards. When quick replacement is needed during maintenance or a precise protection profile is required for critical circuits, this plug-in breaker delivers.
