General Electrics THQB2180ST1 - 80 A, 2-Pole Bolt-On Circuit Breaker | AmpState

Meet the General Electrics THQB2180ST1 — a dependable 80 A, 2-pole bolt-on molded case circuit breaker designed for robust branch circuit protection in panelboards and load centers. Built to keep your electrical network secure, it delivers consistent performance across residential, commercial, and light industrial settings.

Why this breaker stands out

• Secure bolt-on mounting: a rigid, vibration-resistant connection to the bus ensures stability and reduces wear, even in enclosures that experience movement or vibration.
• Thermal-magnetic trip unit: combines precise overload protection from the thermal element with instantaneous short-circuit protection from the magnetic element, providing stable and repeatable protection across varying conditions.
• OEM-ready compatibility: specifically engineered to align with matching General Electrics OEM load centers and panelboards, streamlining installations and replacements.
• Versatile for multiple settings: ideal for residential feeders, commercial subcircuits, and light industrial circuits where reliable protection is essential.
• Two-pole, 80 A configuration: protects two conductors in a single device, enabling coordinated protection for paired circuits within a single panel.

Concrete use cases

• Upgrading panelboards in homes or apartments where a secure, durable connection is critical for long-term reliability.
• Subpanel protection in small to mid-size commercial spaces, where predictable thermal-magnetic trips minimize nuisance trips during peak demand or motor startups.
• Protection for light industrial equipment circuits that require rugged, maintenance-friendly MCCB performance in compact enclosures.

Installation and performance essentials

• Designed for branch circuit overcurrent and short-circuit protection, ensuring quick isolation of fault currents while preserving downstream equipment.
• Compatibility with General Electrics panelboards and load centers offers a seamless fit and consistent trip characteristics across the system.
• Bolts onto standard mounting points for secure, vibration-resistant operation, helping maintain a stable electrical path over time.
