GE THQB32045 - 45 A, 240 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Engineered for dependable branch-circuit protection, the GE THQB32045 is a 45A, 240V, 3-pole bolt-on molded case circuit breaker designed to protect panelboards and load centers. Built to endure the demands of residential, commercial, and light industrial environments, this breaker delivers consistent protection where it matters most.

Why this breaker stands out

• Secure bolt-on mounting provides a rigid, vibration-resistant connection to the bus, reducing movement and ensuring ongoing reliability in demanding installations.
• Thermal-magnetic trip unit delivers stable, repeatable protection—thermal element responds to gradual overloads while the magnetic element provides instantaneous trips during short-circuit events.
• Three-pole design protects three conductors simultaneously, making it suitable for 3-phase systems or multi-wire layouts common in commercial and light industrial setups.
• OEM compatibility is maintained with GE panelboards and load centers, supporting straightforward replacements and retrofit projects.
• Concrete specs for clear application: 45A rating at 240V, designed specifically for branch circuit overcurrent and short-circuit protection.
