GE THQB32080ST1 - 80 A, 240 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Meet the GE THQB32080ST1 — a rugged 80A, 240V, 3-pole bolt-on molded case circuit breaker engineered to protect your electrical system with precision. Designed for dependable branch circuit overcurrent and short-circuit protection, it’s a trusted choice for panelboards and loadcenters across residential, commercial, and light industrial applications.

Why electricians choose the THQB32080ST1

Secure bolt-on mounting delivers a rigid, vibration-resistant bus connection. In environments with equipment movement or vibration, this substantial mounting method helps maintain a solid electrical interface, reducing the chance of loose connections and untimely trips.

Thermal-magnetic trip unit provides stable, repeatable protection performance. The thermal element handles gradual overloads with predictable actuation, while the magnetic element responds quickly to short circuits, delivering fast, reliable shutoff when danger arises.

Designed to be compatible with matching OEM loadcenters and panelboards, this breaker integrates smoothly into existing distributions, supporting streamlined upgrades and replacements without compatibility headaches.
