General Electric THHQB32070ST1 70A 3-Pole 240 V Circuit Breaker

General Electric THHQB32070ST1 is a purpose-built 70A, 3-Pole, 240V circuit breaker crafted to safeguard high-demand, three-phase electrical systems. Identified by part number THHQB32070ST1, this GE component is designed for reliable protection where consistent performance and quick, coordinated trip across all phases matter most.

Designed for three-phase distribution, this 70-amp breaker provides robust overload protection and ensures simultaneous disconnection of all three supply lines. That coordinated protection helps prevent motor or equipment damage and reduces the risk of cascading faults in industrial or commercial electrical setups.

Key advantages that set this GE breaker apart

• 70-amp current rating tailored for heavy-duty, three-phase circuits
• Three-pole design delivers synchronized protection across all phases
• 240-volt operation aligned with common industrial and commercial power systems
• Part number THHQB32070ST1 for precise sourcing, ordering, and replacement
• Brand fidelity: General Electric quality and compatibility within GE panel ecosystems

Ideal use scenarios

Perfect for protecting large motors, industrial drives, HVAC equipment, compressors, and other three-phase loads in warehouses, manufacturing floors, or facilities with GE-compatible panels. If your system runs on 3-phase 240V, this breaker provides a reliable safeguard against overloads and short circuits, helping to minimize downtime and equipment wear.

Practical installation and maintenance tips

• Verify panel compatibility: ensure your GE panel accepts THHQB-series 3-pole breakers and that the 240V three-phase configuration matches your distribution.
• Proper termination: follow manufacturer torque specifications for all terminal connections to maintain secure, low-resistance contacts.
• Match to load requirements: confirm the protected circuit’s continuous load and startup surges are within the breaker's 70A rating to avoid nuisance trips.
• Regular checks: incorporate periodic inspection and testing into your maintenance plan to confirm reliable operation over time.

With the THHQB32070ST1, you’re investing in a dependable, three-phase protection solution that aligns with GE’s engineering standards and your panel’s design. This 70A, 3-Pole, 240V circuit breaker is built to keep critical equipment safe, connected, and ready to perform—so you can focus on productivity without worrying about electrical faults disrupting your operations.
