LS ELECTRIC America, a global leader in power distribution, is proud to highlight its Metasol MS Contactor & Overload Relay platform, a compact low‑voltage solution engineered for high performance, safety, and simplified panel design in industrial and commercial power systems. As North American industries face increasing pressure to modernize aging electrical infrastructure and meet stricter safety standards, the Metasol MS series is engineered specifically for NEMA-influenced U.S. and Canadian requirements, combining high-density power switching with advanced arc-containment technology.
Metasol MS combines a small footprint with robust electrical performance and long service life, giving OEMs, panel builders, and facility engineers a versatile platform that scales from fractional-horsepower loads to high-horsepower motors. One of the most compact footprints in its class helps reduce control panel size and create greater design flexibility in crowded electrical environments, including 600V/690V architectures common in heavy industrial and renewable energy sites. The series supports rated insulation voltages up to 1,000 V on larger frames and covers current ratings from 6 A to 800 A and beyond.
Each contactor can be paired with a directly mountable MT thermal overload relay, creating a compact motor starter with integrated overload protection. MT overload relays are available in multiple trip classes, including Class 10A and 20. The Metasol MS series offers Type II coordination, a critical benchmark for North American engineers; unlike standard Type I setups, Type II helps ensure the contactor remains fully operational after a short-circuit event, reducing Total Cost of Ownership (TCO) and avoiding a replace-on-failure maintenance cycle.
Metasol MS is optimized for easy installation and wiring through its compact design, DIN-rail or screw mounting flexibility, and one-touch DIN-rail connection. A modular, tool-free snap-on accessory system for auxiliary contacts, timers, and mechanical interlocks enables rapid field modifications and helps reduce inventory complexity. A unique four-terminal operating coil allows wiring from both the top and bottom, and built-in 2NO auxiliary contacts on interlocking units often eliminate the need for extra add-on blocks.
Safety and environmental robustness are built into the platform. Most frames feature finger-safe IP20 terminals that help protect personnel from accidental contact with live parts, and the sealed structure prevents arc exposure to the outside. A proprietary sealed arc-extinguishing structure helps protect nearby PLCs and sensitive electronics, while high-efficiency coils minimize heat dissipation and power consumption, extending the lifespan of both the contactor and surrounding sensitive electronics. Metasol MS also applies eco-friendly, cadmium-free contact materials, complies with RoHS environmental standards, and is fully certified to UL, CSA, and CE.
Matching overload relays provide phase-failure protection and ambient temperature compensation, supporting motor longevity in non-climate-controlled and other demanding environments, while increased immunity to high temperature and vibration helps ensure stable operation.
With its combination of high performance, compact design, advanced safety, and integrated accessory ecosystem, the Metasol MS platform gives OEMs, panel builders, and end users a single, scalable foundation for modern motor control. Engineered for millions of operations and compatible with standard 35 mm DIN rails or more complex power systems, the Metasol MS series delivers rugged durability and long service life for heavy industry, HVAC, and sustainable energy applications while helping lower TCO.
