GE THQB32020 - 20A, 3-Pole, Circuit Breaker

Meet GE THQB32020 — a 20A, 3-Pole circuit breaker engineered for reliable overcurrent protection in demanding electrical environments. Designed for panelboards, switchboards, and control panels, this unit helps keep industrial and commercial systems safe and productive by quickly interrupting fault currents and safeguarding motors, feeders, and downstream devices.

Why a 3-Pole design matters

• Balances protection across all three phases, reducing the risk of phase imbalance and collateral equipment damage in 3-phase circuits.
• Simplifies wiring and panel layout by providing a single, unified protective device for multi-phase applications.
• Supports dependable operation in distribution and motor control applications where synchronized switching is essential.

Ideal applications

• Industrial control panels and motor control centers where robust protection is critical.
• Commercial panelboards and switchboards that house multiple three-phase circuits.
• OEM assemblies requiring a compact, reliable 3-pole protection device for 3-phase equipment and machinery.

Key benefits

• Precise current limiting with a 20A rating suitable for protecting branch circuits without excessive interruptions.
• Three-pole configuration delivers synchronized protection across all phases, supporting safer, more predictable operation of motors and downstream loads.
• Rigorous design for dependable performance in distribution panels and motor control centers, enabling longer equipment life and reduced downtime.
• Streamlined integration into standard electrical enclosures and panel assemblies, helping maintain clean, organized panel layouts.
