TKMA836800 - 800Amp Circuit Breaker

TKMA836800 - 800Amp Circuit Breaker

The TKMA836800 is a 3-pole, 800-amp industrial molded-case circuit breaker designed for your dependable overcurrent protection in commercial and industrial electrical distribution systems. Built with an interchangeable thermal magnetic trip unit and internal common trip functionality, this TKM8 breaker is well-suited for applications where reliable interruption and coordinated protection are essential. Its bolt-on mounting design helps you provide a secure installation in compatible switchboards and panel systems, while the included load-side lugs simplify conductor termination during maintenance or replacement projects. Designed for long-term service in demanding electrical environments, this breaker is commonly used as a form, fit, and functional replacement in existing power distribution equipment where maintaining system compatibility matters most.

With interrupting ratings of 22kA at 600VAC, 30kA at 480VAC, and 42kA at 240VAC, the TKMA836800 is built to support a range of medium-voltage industrial and commercial applications. HACR rating compatibility also makes it suitable for heating, air conditioning, and refrigeration equipment installations where compliant circuit protection is required. Its thermal magnetic trip mechanism helps provide both overload and short-circuit protection, helping facilities reduce unnecessary downtime while protecting connected equipment and conductors.
