GE THHQB2180 - 80 A, 240 V, 2-Pole Bolt-On Circuit Breaker | AmpState

The GE THHQB2180 is a dependable 80A, 240V, 2-pole bolt-on molded case circuit breaker designed to protect your electrical system from overcurrent and short circuits. Built for use in panelboards and load centers, this breaker delivers a secure, vibration-resistant connection that keeps critical circuits precisely protected where it matters most.

Why this GE breaker stands out

• Secure bolt-on mounting ensures a rigid, vibration-resistant bus connection, reducing the risk of loose connections that can compromise protection and energize faults.
• Thermal-magnetic trip unit provides stable, repeatable protection by reacting to both sustained overloads (thermal) and instantaneous short-circuits (magnetic) for reliable protection across a range of conditions.
• OEM compatibility designed to pair with matching GE load centers and panelboards, delivering seamless performance with the right trip curves and physical fit.
• Versatile application suitable for residential, commercial, and light industrial environments where dependable branch-circuit protection is essential.

Ideal use cases

Use the GE THHQB2180 to safeguard feeder and branch circuits in cabinets and main distribution panels. It’s an excellent choice when upgrading or replacing an aging breaker, consolidating protection for a dedicated 80A circuit, or expanding a panel with a reliable, easy-to-install bolt-on solution. The two-pole design covers both hot legs together, ensuring simultaneous disconnection in fault conditions and helping maintain electrical balance across the system.
