The General Electric TKMA20800 circuit breaker delivers rugged, industrial-grade protection designed for demanding power systems. With an 800A rating, a two-pole configuration, and a 600V rating, this breaker is built to safeguard high-current circuits in retrofit, maintenance, and replacement projects where exact specifications matter.

• Amperage: 800A
• Poles: 2-Pole
• Voltage: 600V
• Part number: TKMA20800
• Manufacturer: General Electric (GE)

Why this GE circuit breaker stands out

Designed to align with precise specifications, the TKMA20800 offers reliable, repeatable performance for high-demand installations. The two-pole design ensures simultaneous disconnection of both conductors in 600V circuits, which is essential for safe service isolation and protection of equipment and personnel in industrial environments.

Ideal use cases

Use the TKMA20800 for

• Maintenance and service upgrades on GE panels and compatible switchgear
• Retrofits where an exact 800A, 2-pole, 600V specification is required
• Replacement of aging or non-functioning breakers in high-current systems

How to verify compatibility

Before ordering, confirm fit and ratings using the part number TKMA20800 as the primary reference. This ensures your panel, enclosure, and wiring are all matched to the same industrial standards and safety requirements. If your documentation specifies GE standards or a direct GE replacement lineage, this breaker is positioned to meet those expectations.

Practical guidance for installation and use

Work with a licensed electrician to install, test, and commission the breaker within your electrical distribution system. Ensure all local codes and manufacturer instructions are followed. Keep case labels, rating plates, and documentation accessible for future maintenance and audits. For ongoing reliability, pair this breaker with properly rated conductors and protective devices that align with your 600V system specifications.

What to expect in performance and reliability

General Electric engineering underpins durable performance in this 800A, 2-Pole, 600V model. By matching the exact part number TKMA20800, you minimize the risk of incompatibility and ensure consistent protective behavior, efficient maintenance cycles, and a clear, traceable replacement path for future service needs.
