General Electrics THJK636350 - 350 A, 3-Pole Bolt-On Circuit Breaker | AmpState

Discover the General Electric THJK636350—a 350 A, 3-pole bolt-on molded case circuit breaker designed to deliver dependable overcurrent and short-circuit protection for panelboards and load centers. Built to withstand demanding electrical environments, it provides consistent performance across residential, commercial, and light industrial applications.

Why this GE 3-Pole Bolt-On Breaker stands out

• Secure bolt-on mounting creates a rigid, vibration-resistant connection to bus bars, reducing movement and arcing in high-load installations.
• Thermal-magnetic trip unit offers stable thermal overload protection with instant magnetic tripping for short circuits, safeguarding conductors and equipment.
• Three-pole configuration supports balanced three-phase circuits, simplifying wiring and reliability in multi-branch systems.
• OEM-compatible design is engineered to pair with matching GE OEM load centers and panelboards for seamless fit and consistent trip characteristics.
• High-capacity protection with a 350 A rating is ideal for larger feeders and demanding electrical layouts where smaller breakers fall short.
• Molded case durability provides solid insulation and reliable performance in tight panel spaces, with robust protection against environmental factors.

Practical use cases

- Upgrading or replacing failing breakers in GE panelboards and load centers used in offices, retail spaces, and light industrial facilities. - Protecting large feeders for critical equipment such as HVAC systems, pumps, or compressed-air systems where reliable 3-phase protection is essential. - Subpanel or main feeder protection in commercial environments requiring a strong, compatible 3-pole 350 A solution.

Installation and compatibility tips

Verify that your panel is rated for 350 A and that the THJK636350 matches the trip curve and mounting expectations of your GE load center. Use proper torque on mounting hardware to ensure a solid bus connection, minimizing vibration-related issues. This bolt-on design simplifies alignment and provides a secure, long-lasting connection when paired with the appropriate GE OEM panel hardware and accessories.
