General Electric THQB32045ST1 45A 3-Pole 240 V Circuit Breaker

Meet the General Electric THQB32045ST1 45A 3-Pole 240 V Circuit Breaker — a purpose-built protection device designed to safeguard your 240-volt power distribution with precision. Identified by Part Number THQB32045ST1, this unit is a dedicated member of GE’s THQB family, crafted for reliable performance in multi-conductor, high-demand circuits.

Key specifications

• Current rating: 45 A
• Poles: 3
• Voltage rating: 240 V
• Part Number: THQB32045ST1

Ideal applications

• Protects three-conductor 240V circuits feeding motors, pumps, conveyors, or other heavy equipment.
• Suitable for three-pole 240V feeders in GE THQB-compatible panels and assemblies.
• Effective for safeguarding distributed loads where multiple hot lines must trip simultaneously to prevent unsafe conditions.

Why choose the THQB32045ST1

• Precise compatibility: Engineered to fit GE panels that accept THQB-series breakers, ensuring a clean, code-compliant installation.
• Targeted protection for 240V systems: With a 45A rating, it is designed to shield moderate-to-high current loads from overloads and short circuits on 240V three-wire circuits.
• Three-pole design for balanced safety: The 3-pole configuration interrupts all hot conductors at once, reducing the risk of uneven phase conditions and enhancing overall electrical safety for multi-conductor circuits.

Practical installation and usage tips

• Verify that your panel accepts THQB breakers and that the THQB32045ST1 is the correct rating for your load requirements.
• Plan for proper wiring to the three hot terminals and ensure all connections are secure before energizing the system.
• Use this breaker to protect critical loads on 240V circuits, such as motors and other high-current equipment, to help minimize damage from overloads and faults.
• Consult a licensed electrician for panel compatibility, wiring, and local electrical codes to ensure a safe, compliant installation.

With the General Electric THQB32045ST1, you get a dedicated 45-amp, three-pole solution tailored for 240 V systems that demand reliable, coordinated protection across all hot lines. A practical choice for engineers, electricians, and facility managers seeking dependable circuit protection that aligns with GE’s trusted THQB lineup.
