THKMA836350WL - 350Amp Circuit Breaker

THKMA836350WL - 350Amp Circuit Breaker

The THKMA836350WL Circuit Breaker is a 350-amp, three-pole industrial molded-case circuit breaker for your compatible commercial and industrial electrical distribution systems. Featuring a THKM8 breaker configuration, cable-in/cable-out (lug-lug) connection arrangement, interchangeable thermal-magnetic trip unit, and internal common-trip operation, this breaker provides the electrical and mechanical characteristics needed for applications requiring a matching 350A protective device. Its specified interrupting capacities are 65kA at 240VAC, 35kA at 480VAC, and 25kA at 600VAC, allowing electrical professionals to evaluate the breaker against the operating voltage and available fault current of an existing installation. The THKMA836350WL is also HACR rated and includes both line-side and load-side lugs, an important distinction when identifying a compatible replacement for an established electrical system.
