Westinghouse MC3800WK is a molded case circuit breaker designed for providing a main disconnect and short-circuit protection in three-phase electrical systems. It features a 600V AC voltage rating and an 800A continuous current rating, with a robust 30kA interrupting capacity at 480V to handle high fault currents. The unit is constructed as a three-pole, bolt-on device with a non-automatic protection function, meaning it requires manual operation to interrupt the circuit and does not provide overcurrent protection. This SELTRONIC family breaker complies with relevant industry standards for safety and performance in industrial power distribution. It is typically applied in panelboards, switchboards, and industrial control equipment where a reliable main circuit breaker is required.
