General Electric THJK426300LL Circuit Breaker is a purpose-built protection device for high-demand electrical systems. With a 300A amperage rating and a 2-pole configuration, it protects two energized conductors in circuits up to 600V. It’s the dependable choice for maintenance, retrofit, and replacement tasks where exact GE specifications are required.

Key specifications

  • Amperage: 300A
  • Poles: 2-Pole
  • Voltage: 600V
  • Part number: THJK426300LL
  • Brand: General Electric (GE)

Why this matters: Using the exact part number THJK426300LL ensures proper fit and electrical ratings, reducing the risk of incompatibility in GE-branded panels and equipment. This is especially important during scheduled maintenance or when performing a retrofit to meet current protection needs.

Best use cases

  • Maintenance: keep a ready GE-approved replacement on hand to minimize downtime.
  • Retrofit: upgrade or restore protection in GE panels requiring a 300A, 2-pole, 600V breaker.
  • Replacement: swap out a failed unit with a direct, compatible GE part to restore electrical protection quickly.

Practical tips for installation and selection:

  • Always confirm fit and ratings before ordering. The THJK426300LL part number is the best reference for compatibility.
  • Handle with standard electrical safety precautions—disconnect power and follow local codes during replacement.
  • Keep a few GE THJK-series breakers on hand for planned maintenance in busy service environments.
