Menlo Microsystems’ (Menlo Micro) MEMS-based circuit-breaker modules demonstrated their ability to support high-voltage, megawatt-scale applications under challenging real-world conditions during field trials conducted as part of the U.S. Navy’s 10 MW Advanced Circuit Breaker Development Program. The trials evaluated a 1,000-V, 500-A panel system built from four of Menlo’s 1,000-V/125-A MEMS switch modules, under challenging real-world conditions. Unlike semiconductor-based switches, Menlo’s compact chip-size arrays of metal-to-metal MEMS switches enable virtually lossless switching with minimal heat generation and support very high voltages. Electronic Design provided a closer look at the technology in the April 2025 edition of our PowerBites blog. You can also see a demonstration of these capabilities in a demonstration that editor Alix Paultre recorded at PCIM 2026 for our Tech Exchange video series (see video below).
