General Electric | TKMA21200 | Circuit Breaker | 1200A | 2-Pole | 600V

Meet the General Electric TKMA21200 Circuit Breaker — a purpose-built, high-capacity protection device designed for demanding electrical applications. With a 1200A amperage rating and 2-pole configuration at 600V, this breaker is engineered for reliable main- or feeder-protection in retrofit, maintenance, and replacement projects where exact specifications matter.

Overview and specifications

• Amperage: 1200A
• Poles: 2-Pole
• Voltage: 600V
• Brand and part: General Electric, TKMA21200

Why this GE TKMA21200 stands out

Unlike generic substitutes, this GE circuit breaker is a precise reference point for compatibility in GE panels and systems that require the TKMA21200 form factor. The 2-pole design protects both conductors in two‑wire or multi‑wire circuits, simplifying installation and ensuring balanced protection across the circuit. The 1200A rating makes it suitable for higher-current feeds, service entrances, and sizable branch circuits where robust overcurrent protection is essential.

Ideal use cases

• Maintenance and service upgrades for aging GE panels that require a matching 2-pole, 600V device with a 1200A rating
• Retrofit projects where exact part compatibility is non-negotiable
• Replacement of worn or failed breakers in commercial or industrial environments

Compatibility, installation, and best practices

Before ordering, verify fit and ratings to ensure a seamless replacement. The TKMA21200 part number is the primary reference for compatibility, so cross-check it against your panel schedule or service documentation. For installers, handle with standard electrical safety procedures, disconnect power before work, and follow panel manufacturer guidelines to ensure correct mounting, bus connection, and labeling.

Practical guidance and outcomes

Choosing the TKMA21200 means investing in predictable protection for critical circuits. Users can expect straightforward replacement in compatible GE assemblies, reduced downtime during service intervals, and maintained protection integrity for high-current feeders. This is a solution built for reliability in demanding environments, from facilities management to industrial operations.
