Why this GE breaker stands out

OEM authenticity matters when protecting heavy electrical loads. The TKMA2Y1000 is engineered to align with GE panel boards and accessories, reducing the guesswork during retrofits or replacements. Its 2-pole design ensures simultaneous tripping on both conductors, delivering consistent protection for feeders and main-distribution circuits. Choosing this exact General Electric part helps preserve the electrical characteristics of your system, minimizes compatibility issues, and supports safer, more predictable operation in industrial settings.

Ideal use cases

• Retrofit projects where the existing equipment requires a precise GE 1000A, 2-pole, 600V breaker
• Maintenance replacements to restore original protection characteristics in GE panels
• Replacement part for heavy-load feeders in commercial or light-industrial environments

Installation and compatibility considerations

Before ordering, confirm fit and ratings match your equipment. The part number TKMA2Y1000 is the best reference for compatibility, so cross-check it against your panel labeling and service documentation. When installing, follow your facility’s electrical codes and GE installation guidelines, and consider professional installation to ensure proper seating, clearance, and safe operation.

Practical tips for best results

• Keep a spare TKMA2Y1000 on hand for planned maintenance to minimize downtime.
• Verify that the replacement breaker aligns with the panel’s listed configurations to maintain electrical predictability.
• Inspect mounting hardware and bus connections during replacement to prevent loose connections and nuisance trips.
