General Electric | TJK436125LL | Circuit Breaker | 125A | 3-Pole | 600V | Bolt-On

If you’re maintaining, retrofitting, or replacing a GE electrical panel, the General Electric TJK436125LL Circuit Breaker is built to meet demanding 3-phase distribution needs. This 125A, 3-pole bolt-on unit delivers reliable interruption for industrial and commercial circuits up to 600V, keeping systems safe and downtime minimal.

• Amperage: 125A — suitable for protecting feeders and downstream equipment on 3-phase circuits.
• Configuration: 3-Pole — handles all three phases in a single device for coordinated protection.
• Voltage rating: 600V — appropriate for medium-voltage distribution inside panelboards and switchgear environments.
• Mounting style: Bolt-On — designed for secure, field-assembly into compatible GE panels, offering solid contact and dependable performance.
• Part number reference: TJK436125LL — use this exact model as the best cross-reference for compatibility and replacements.

Why this matters: in any service or retrofit project, selecting the correct breaker isn’t just about current rating—it’s about ensuring the exact mechanical fit, electrical characteristics, and trip coordination with neighboring devices. The TJK436125LL is purpose-built for GE systems that require a bolt-on, 3-pole solution with a 125A rating and a 600V maximum, delivering consistent protection for motors, feeders, and distribution blocks.

Ideal use cases include:

• Replacing a failed breaker in GE panelboards or switchgear that accepts bolt-on units.
• Retrofits where a 125A, 3-pole, 600V bolt-on solution aligns with existing bus bars and mounting patterns.
• Maintenance shoring for critical 3-phase loads in commercial facilities, manufacturing floors, and process lines.

How it helps you outperform generic options:

• Exact model clarity with the TJK436125LL ensures you’re swapping the right unit for your GE equipment, reducing guesswork and compatibility risk.
• Three-phase protection with a single device simplifies wiring, reduces space, and supports coordinated shutdown across all phases.
• Bolt-on mounting provides robust mechanical stability in high-vibration environments where plug-in breakers might loosen over time.

Practical tips for installation and ordering:

• Always confirm fit and ratings in your equipment datasheet before purchasing. The part number TJK436125LL is the strongest compatibility reference.
• Store replacement breakers in a clean, dry environment to prevent corrosion on terminals and connectors.
• Handle with care when connecting to bus bars; ensure all mounting hardware is secure to maintain proper electrical contact.

Whether you’re performing routine maintenance, performing a retrofit, or replacing a failed device, the GE TJK436125LL bolt-on circuit breaker delivers reliable, rated protection for 3-phase circuits up to 600V. It’s the specific, model-accurate choice that aligns with GE panel systems and helps maintain safe, uninterrupted operation of your electrical distribution.
