THKMA826800WL - 800Amp Circuit Breaker

THKMA826800WL - 800Amp Circuit Breaker

The THKMA826800WL Circuit Breaker is an 800-amp, two-pole industrial molded-case breaker for your compatible commercial and industrial electrical distribution systems. Featuring a THKM8 breaker configuration, interchangeable thermal-magnetic trip unit, internal common-trip operation, and cable-in/cable-out (lug-lug) connections, this breaker provides defined electrical and mechanical characteristics for applications requiring a matching 800A circuit protection device. Its interrupting capacities are 65kA at 240VAC, 35kA at 480VAC, and 25kA at 600VAC, which are important when evaluating compatibility with an existing electrical installation. The THKMA826800WL is also HACR-rated and includes both line-side and load-side lugs, supporting its specified conductor-connection arrangement.
