Municipal Trucks
Each municipality relies on public works vehicles. Littelfuse helps flatbeds, water trucks, and service, utility, and crane bed trucks operate optimally by producing dc disconnect switches and starter solenoids for fleet vehicles. We also produce diesel heaters that enhance efficiency and environmental compliance, as well as overcurrent and overvoltage protection for emergency/warning lights.
Tractor-Trailers
When tractor-trailers and tanker trucks work, so does the economy. Littelfuse keeps the literal wheels of commerce turning by making overcurrent and overvoltage protection devices optimized for use in diesel or electric vehicles. We also make dc connectors, sockets, and plugs, as well as electronics for sensors, cameras, LED screens, and Wi-Fi that enable advanced driver assistance systems (ADAS).
