• Shunt-trip capability enables remote tripping, adding an essential layer of safety for emergency shutdowns and coordinated protection schemes.
• Three-pole design supports three-phase systems, providing balanced protection across all hot conductors.
• 100 A, 240 V rating matches common commercial and industrial distribution needs while maintaining reliable short-circuit protection.
• Original BOM alignment ideal for replacement projects and stocking spares that must match the original part number (THQB32100ST1) to ensure seamless compatibility.
• AmpState availability – a trusted source for authentic GE parts and compatible replacements, with guidance to confirm fit.

Why this breaker matters in real-world setups

For facility managers, service technicians, and electrical contractors, this GE THQB32100ST1 is more than a component—it’s a reliable safeguard that simplifies maintenance workflows. If you’re upgrading an older panel or stocking parts to minimize downtime, the 3P 240V configuration with bolt-on mounting ensures you can perform fast, accurate replacements while preserving system integrity. The shunt-trip feature is particularly valuable in scenarios requiring remote control of power to feeders or equipment racks, such as data centers, manufacturing lines, and critical service areas.

Ideal use cases and practical scenarios

• Replacing worn or obsolete breakers in existing GE panelboards and load centers without reconfiguring the distribution layout.
• Stocking a spare that precisely matches the original part number to maintain BOM continuity during audits or rebuilds.
• Implementing remote-tripping capabilities for safety interlock systems or emergency shutdown protocols in industrial settings.
• Designing three-phase protection for commercial electrical distributions where fast, reliable trip performance is essential.
