Description
Part of the Series C MDS frame lineup, this 800-ampere molded case switch provides essential circuit isolation for industrial facilities. The device installs into Eaton and legacy Westinghouse M-Frame enclosures or motor control centers, functioning primarily as a disconnect. While it does not offer thermal overload protection, the switch includes a self-protecting high instantaneous magnetic trip mechanism to handle severe faults. It serves as a drop-in replacement for the MS360800.Specifications

Mathews Electric just loves SuperBreakers! Especially, Michael David. He always comes through for us. The rest of the team is great as well, but Michael just knows that when we call, it is usually for an emergency situation.
