General Electrics TQD32100ST1 - 100 A, 3-Pole Bolt-On Circuit Breaker | AmpState

Meet the General Electrics TQD32100ST1 — a 100 A, 3-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit protection in panelboards and load centers. Built for performance in real-world electrical environments, this unit keeps critical systems safe from overcurrent and short circuits while withstanding the vibrations and demands of everyday operation.

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection that stays tight over time, reducing the risk of loose connections and intermittent trips.
• Thermal-magnetic trip unit delivers stable, repeatable protection. The thermal element responds to overloads with predictable timing, while the magnetic component provides fast interruption during high‑fault events, safeguarding wiring and devices.
• OEM-compatible design is engineered to pair with matching General Electrics panels and OEM load centers, ensuring a clean fit and reliable performance in existing installations.
• 3-pole configuration is ideal for three-phase power systems commonly found in commercial and light industrial applications, delivering balanced protection for multi‑phase equipment.
• Rugged molded case construction stands up to the needs of residential, commercial, and light industrial environments, providing durable protection for critical circuits.

Why this breaker works for you

If you’re upgrading or maintaining panelboards and load centers that require robust, 3‑phase protection, the TQD32100ST1 provides a purpose-built solution. Its bolt-on design minimizes connection looseness in environments with vibration or movement, while the thermal-magnetic trip set delivers predictable responses to overloads and faults. This unit is especially well-suited for service entrances, commercial distribution panels, and light industrial panels where reliable protection and OEM compatibility matter most.

Ideal use scenarios

• New installations in commercial spaces with three‑phase equipment and 100 A feeder protection needs
• Retrofits and replacements in OEM panelboards where exact form factor and trip characteristics are required
• Protection of motor circuits and other 3‑phase loads against overcurrent and short circuits
• Panel maintenance programs that prioritize vibration resistance and long-term connection integrity

Practical tips for installation and care

• Confirm panelboard compatibility with GE TQD series devices before installation to ensure the bolt-on mounting aligns with the bus structure.
• Torque the mounting fasteners to the manufacturer’s specification to maintain the integrity of the rigid bus connection.
• During replacement, verify that the service bus rating and interrupting capacity align with your system’s fault current to ensure proper coordination.
• Keep spare units like the TQD32100ST1 on hand for quick field replacements, reducing downtime in critical commercial environments.
