GE THQB32080 - 80 A, 240 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The GE THQB32080 is a purpose-built, three-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit protection in panelboards and load centers. With a robust bolt-on mounting, it provides a rigid, vibration-resistant connection to the bus, reducing movement that can lead to loose contacts over time. Paired with a thermal-magnetic trip unit, it delivers stable, repeatable protection against both overloads and short circuits across a range of operating environments.

• Secure bolt-on mounting: Creates a rock-solid bus connection that resists vibration and movement in busy electrical rooms and equipment spaces.
• Thermal-magnetic trip unit: Delivers consistent protective response, adjusting to temperature and current variations to prevent nuisance trips while ensuring safety.
• 3-pole configuration: Ideal for balanced three-phase systems, enabling reliable protection for commercial and light industrial applications.
• 80A at 240V: Exactly suited for branch circuits requiring solid overcurrent and short-circuit protection without over- or under-guarding current capacity.
• OEM panel compatibility: Engineered to align with GE and compatible OEM load centers and panelboards, simplifying replacement and upgrades.
• Diversified use cases: Suitable for residential, commercial, and light industrial installations where compact, dependable protection is essential.

Why this GE THQB32080 stands out is not just its specs—it’s how those specs translate into real-world reliability. In environments where panels endure frequent vibration, temperature swings, or dense wiring, this bolt-on breaker maintains a tight bus connection and predictable tripping behavior. The combination of a thermal-magnetic trip method and a sturdy 3-pole design means you get fast fault interruption and minimized downtime, whether you’re upgrading an aging panel or installing a new, OEM-compatible solution.

Applications and ideal scenarios

Use the THQB32080 to protect critical branch circuits in:

• Residential panelboards undergoing upgrades where three-phase protection is required for particular equipment or subpanels.
• Commercial electrical rooms with moderate to heavy electrical loads and equipment subject to vibration or movement.
• Light industrial setups that demand reliable overcurrent protection without extensive integration work.
