GE THQB32090ST1 - 90 A, 240 V, 3-Pole Bolt-On Circuit Breaker | AmpState

GE THQB32090ST1 is a 90A, 240V, 3-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers.

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection, helping prevent loose connections that can lead to nuisance trips or degraded protection in busy electrical panels.
• Thermal-magnetic trip unit delivers stable, repeatable protection by combining both thermal (overload) and magnetic (short-circuit) responses for a wide range of load profiles.
• OEM compatibility designed to work with matching GE OEM loadcenters and panelboards, ensuring a seamless fit and reliable trip coordination.
• Versatile across environments suitable for residential, commercial, and light industrial applications where durable, reliable 3-pole protection is needed at 240V.

What it protects The THQB32090ST1 guards three-phase or 240V branch circuits against overcurrent and short-circuit events, helping to prevent equipment damage and minimize downtime in electrical systems.

Ideal use cases

• Upgrading or replacing aging breakers in GE panelboards and load centers to maintain safe, code-compliant protection.
• Providing robust 3-pole protection for 240V circuits in small commercial spaces, workshops, and light industrial settings.
• Motor and equipment circuits where reliable trip performance is critical, such as HVAC, compressors, conveyors, and processing equipment.
