Reliable Solid-State Contactors for OEM Panels

Solid‑State Contactors (SSCs) for OEM Control Panels Littelfuse solid‑state contactors (SSCs) deliver the reliability of solid‑state switching in a contactor‑style format optimized for OEM control panels. Designed for higher‑power and multi‑phase loads, SSCs provide long operational life without mechanical wear, making them well suited for demanding industrial environments. Using the same solid‑state technology as SSRs, Littelfuse SSCs support precise control of heaters and motors in applications such as industrial ovens, HVAC systems, plastics machinery, automation equipment, and power distribution panels. DIN‑rail mounting and slim footprints simplify panel layouts and support modular machine architectures. Features such as zero‑cross switching reduce electrical noise and thermal stress, while integrated heatsinks, IP20 touch‑safe covers, and push‑in or screw‑terminal wiring streamline installation and assembly. Available in 1‑pole to 3‑pole configurations — including reversing contactors — SSCs support forward/reverse motor control and flexible system design. Built to withstand heat, surge events, and frequent cycling, Littelfuse SSCs help OEMs improve uptime, reduce maintenance, and scale designs across product platforms. OEM customization options are available to meet specific machine requirements.
