TKMA826500 - 500Amp Circuit Breaker

TKMA826500 - 500 Amp Circuit Breaker

The TKMA826500 is a 500-amp, 2-pole circuit breaker used in your commercial and industrial electrical systems where dependable protection is needed for higher-capacity equipment. It features a thermal magnetic trip unit that responds to overloads and short circuits, helping protect connected systems from electrical damage and unexpected downtime. With its bolt-on design, this breaker is commonly used as a replacement in existing TKM8 installations where a close fit and ratings are important. The internal common trip mechanism allows both poles to trip together when needed, and the included load-side lugs make field installation easier. The HACR rating also makes it suitable for HVAC and refrigeration applications found in commercial buildings and industrial facilities. The TKMA826500 is often installed in manufacturing plants, large panelboards, distribution equipment, and other demanding electrical environments. Its solid construction and straightforward design make it a practical option for keeping older systems operating safely and reliably without requiring major equipment changes.
