General Electric | TJK426350 | Circuit Breaker | 350A | 2-Pole | 600V | Bolt-On

Meet the General Electric TJK426350 circuit breaker—a rugged, high-current two-pole unit crafted for demanding electrical systems. Rated at 350A and 600V, this bolt-on breaker delivers dependable overcurrent protection in industrial and commercial panels where stability and precision matter.

• Amperage and voltage you can trust: 350A capacity paired with a 600V rating makes this breaker suitable for heavy-duty feeders and main-limb protection in GE installations.
• Two-pole design for coordinated protection: Simultaneous disconnection of both hot legs enhances safety, trips together, and simplifies panel troubleshooting.
• Bolt-On mounting: Secure, vibration-resistant installation that pairs well with compatible GE enclosures and retrofit projects.
• Part reference for compatibility: The exact match is TJK426350—use this part number to verify fitment within your equipment.
• Ready for maintenance, retrofit, and replacement: Ideal for upgrading existing panels, replacing aging breakers, or performing service work where the specs align.

Who benefits most: electrical contractors, facilities engineers, and maintenance teams working in industrial facilities, manufacturing floors, or large commercial sites where reliable, high-current protection is essential. This GE breaker is suited for use in systems that require a robust bolt-on solution and a precise 350A rating, backed by GE’s engineering standards.

Why this breaker solves real problems: Instead of generic, one-size-fits-all protection, the TJK426350 provides a deliberate fit for applications demanding a 350A, 2-pole, 600V bolt-on device. Its design minimizes installation variables, enabling consistent performance across demanding environments and reducing panel downtime during renewals or upgrades.

Practical tips for installation and planning:

• Before ordering, confirm fit and ratings—the part number TJK426350 is your best compatibility reference.
• Prepare the panel for bolt-on mounting by inspecting mounting holes and conductors for clean, unobstructed connections.
• De-energize and discharge all circuits before servicing; follow your local electrical codes and GE panel guidelines for safe installation.
• Document the replacement in the panel log, noting the amperage, voltage rating, and polarity to ensure future maintenance accuracy.
