GE THQB32030ST1 - 30 A, 240 V, 3-Pole Bolt-On Circuit Breaker | AmpState

GE THQB32030ST1 is a 30A, 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. Built to perform consistently across varying load conditions, this unit integrates smoothly with GE OEM components for a cohesive, reliable electrical system.

• Bolt-on mounting provides a rigid, vibration-resistant bus connection to maintain solid electrical continuity even in environments with steady vibrations or movement.
• Thermal-magnetic trip unit combines precise thermal overload protection with fast magnetic interruption, delivering stable, repeatable protection against both sustained overloads and sudden short circuits.
• Three-pole design ensures simultaneous disconnection of all hot conductors in 3-phase circuits, enhancing safety and protecting equipment in multi‑phase systems.
• 30A, 240V rating tailored for residential, commercial, and light industrial applications where reliable 3‑pole protection is required.
• OEM-compatible engineered to complement matching GE panelboards and load centers for a clean, plug-and-protect installation without compatibility concerns.

Why this breaker matters in your electrical system

The dual-action trip mechanism provides predictable protection: the thermal element responds to prolonged overcurrent, while the magnetic element rapidly clears severe faults. The result is consistent trip performance across temperature swings and varying supply conditions, helping to minimize downtime and protect downstream equipment.

Ideal use cases

• New installations or panel upgrades in commercial spaces that rely on 3-phase equipment.
• Subpanels and main distribution panels requiring reliable multi-pole protection for three hot legs.
• HVAC systems, pumps, conveyors, and other 240V loads common in light industrial settings where dependable fault isolation is critical.

Installation and compatibility notes

For optimal performance, mount the THQB32030ST1 with secure bolt-on attachment to a compatible GE panelboard or load center. Verify that the panel is rated for 3-pole molded case breakers and that bus connections are clean and tightened to spec. This device is intended specifically for branch-circuit overcurrent and short-circuit protection and should be installed by qualified personnel in accordance with local electrical codes.
