General Electrics THQD32200ST1 - 200 A, 3-Pole Bolt-On Circuit Breaker | AmpState

General Electrics THQD32200ST1 is a 200A, 3-pole bolt-on molded case circuit breaker designed to deliver dependable branch-circuit overcurrent and short-circuit protection in panelboards and load centers.

Why this breaker stands out

• Secure bolt-on mounting: a rigid bus connection that stays stable even in vibration-prone environments, reducing the risk of loose contacts, overheating, or unwanted trips.
• Thermal-magnetic trip unit: combines thermal overload sensing with instantaneous magnetic tripping for stable, repeatable protection across a range of temperatures and fault conditions.
• OEM compatibility: engineered to fit and function with matching General Electrics OEM load centers and panelboards, ensuring reliable fit and electrical performance.
• 3-pole design for three-phase systems: ideal for residential, commercial, and light industrial applications that require balanced protection of all three phases.
• 200 Amp, molded case construction: robust, compact design built for durable service in panelboards and load centers.

Where and how you’ll use it

Use the THQD32200ST1 as branch-circuit protection or as a main feeder device in General Electrics panelboards and load centers. Its three-pole bolt-on design provides a secure mechanical fit and a solid electrical connection—especially valuable in installations subject to vibration or frequent operation.

Use-case scenarios

• Upgrading or replacing a worn-out breaker in a residential or light commercial service panel that requires a 200A, 3-pole bolt-on solution.
• Feeding three-phase equipment in commercial spaces (such as motors and HVAC controls) that demand reliable short-circuit protection.
• Installing a rugged main or feeder breaker in new construction where OEM panel compatibility matters for a clean, bolt-on mounting.

Practical considerations

• Confirm panel compatibility with General Electrics THQD32200ST1 to ensure correct fitment and torque specifications for bolt-on mounting.
• In maintenance cycles, routinely inspect bus connections and mounting hardware to preserve low-resistance contacts and reliable operation.
• Follow local electrical codes for proper sizing, protection requirements, and installation practices in your service panel or load center setup.
