The FR50-750 is a line of membrane operated switches offered by Memcor-Truohm. These switches are designed to provide accurate switching of high power loads up to 750amps, while also utilizing Memcor's patented self-actuating Truohm technology. This technology uses a semiconductor membrane that is charged and discharged depending on the flow of current, resulting in precise switching of the load with minimal operator intervention. This allows the switch to provide effortless switching, even with high power loads.
