GE THQB2190 - 90 A, 240 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Engineered for durable, reliable protection of electrical distribution systems, the GE THQB2190 is a 90A, 240V, 2-pole bolt-on molded case circuit breaker. Designed to live in panelboards and load centers, it delivers dependable overcurrent and short-circuit protection for residential, commercial, and light industrial circuits.

Key features

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection, reducing connection wear and maintaining consistent performance in demanding environments.
• Thermal-magnetic trip unit delivers stable, repeatable protection by responding to both overload and fault currents, helping prevent nuisance trips while safeguarding equipment.
• 2-pole, 90A at 240V configuration protects two energized conductors for balanced, effective circuit isolation.
• Compatibility with matching OEM load centers and panelboards ensures a seamless fit and reliable integration with existing GE equipment.
• Bolt-on mounting simplifies installation in panels designed for this style, delivering strong mechanical retention and long-term reliability.

Why it matters

The THQB2190 isn’t just a breaker—it’s a centerpiece for dependable electrical protection. The combination of a bolt-on, vibration-resistant connection and a thermal-magnetic trip mechanism provides predictable performance even under fluctuating loads or brief surge conditions. This translates to fewer unexpected trips, safer shutdowns when faults occur, and easier maintenance for panel upgrades or new installations.

Ideal use cases

• Residential panel upgrades where bolt-on protection is specified or required.
• Commercial and light industrial subpanels needing robust branch-circuit protection with a secure mounting method.
• Retrofits or replacements in GE OEM panelboards and load centers to maintain system compatibility and performance.
