GE THHQB32015 - 15 A, 240 V, 3-Pole Bolt-On Circuit Breaker | AmpState

GE THHQB32015 is a 15A, 240V, 3-pole bolt-on molded case circuit breaker engineered for dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. Built to withstand vibration and movement, it delivers reliable interruption when you need it most.

Designed for stable, repeatable protection, the thermal-magnetic trip unit responds to both sustained overloads and instantaneous short circuits. This means fewer nuisance trips during brief surges and faster, coordinated shutoff during faults, helping protect wiring, devices, and the broader electrical system.

Key advantages

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection that stays tight even in busy panels.
• Thermal-magnetic trip technology combines time-delay overload protection with instantaneous magnetic trip for fast fault clearance.
• 3-pole, 240V design ensures simultaneous interruption of all conductors in 3-phase circuits, reducing arc potential and enhancing safety.
• OEM-compatible—specifically designed to be compatible with GE OEM load centers and panelboards, enabling straightforward replacements or upgrades.
• Versatile for multiple sectors—well-suited for residential panels, commercial distribution boards, and light industrial applications.
