General Electric | TKMA21200WL | Circuit Breaker | 1200A | 2-Pole | 600V

The General Electric TKMA21200WL circuit breaker is a robust, high-current protection device designed for demanding electrical installations. With a 1200A rating across 2 poles at 600V, it’s built to safeguard large feeders and equipment in industrial, commercial, and retrofit projects.

Designed for maintenance, retrofit, and replacement scenarios where exact specs matter, this GE breaker helps you keep critical power on track without compromising safety.

Key specifications

• Amperage: 1200A
• Poles: 2-Pole
• Voltage: 600V

Why choose the TKMA21200WL? It’s engineered to handle high-load circuits with reliability, providing clear, predictable protective behavior when standard loads spike or short-circuit. The two-pole configuration ensures simultaneous interruption of both hot lines, protecting equipment and reducing arcing risks in grounded and 3-phase systems.

Use cases and ideal applications

• Retrofit projects upgrading older panels to current GE-compatible breakers while preserving existing wiring and bus configurations.
• Service panel updates in facilities with 600V distribution or large motor loads that demand 1200A protection.
• Maintenance replacements in industrial control rooms, processing plants, or data-center support racks where maximizing uptime matters.

Important compatibility notes: Confirm fit and ratings before ordering. Part number TKMA21200WL is the best reference for compatibility. This ensures you match the geometry, terminal size, and electrical characteristics to your panel and feeders.

Installation and best practices

• Have a licensed electrician perform the installation to ensure proper panel compatibility and safe termination of conductors.
• Verify that your panel’s rating and bus assembly can accommodate a 1200A, 2-pole device at 600V.
• Follow the panel manufacturer's torque specs and safety procedures to secure the breaker without damaging connectors.
• Keep this spare on hand for quick replacement in critical applications to minimize downtime.

Compared to lower-amperage or generic breakers, the TKMA21200WL is purpose-built for high-demand environments. Its GE engineering heritage supports consistent response under fault conditions and long-term reliability when used within its specified ratings, helping you protect expensive equipment, minimize electrical faults, and simplify maintenance planning.
