Electric vehicles and industrial electronic control systems demand reliable, high-performance power management solutions. Littelfuse High-Voltage DC Contactor Relays are engineered to meet those demands with robust switching capability, long electrical life, and circuit protection across a wide range of applications, including Hybrid Electric Vehicles (HEVs), Battery Electric Vehicles (BEVs), eMobility, electric maintenance and transport vehicles, material handling equipment, industrial machinery, and energy storage systems.

Our portfolio includes models with continuous current ratings from 30A to 800A and maximum voltage ratings up to 1800V DC, supporting both low- and high-power system requirements. A full range of configurations are available to meet specific design needs, including options with non-polarized or polarized contacts, auxiliary contacts, and coil-economizer technologies such as pulse-width modulation (PWM) and double-coil economizer designs to reduce power consumption and heat generation.

Also designed for use in industrial applications, such as EV charging infrastructure, battery packs, uninterruptible power supplies, DC fast-charging, motor control, circuit insulation, circuit protection, and safety-critical systems, our High-Voltage DC Contactors deliver safe, reliable performance in demanding environments.
