New DIN rail and panel mount models protect single- and three-phase heating and motor control applications
ROSEMONT, Ill, September 17, 2026—Littelfuse, Inc. (NASDAQ: LFUS), a diversified, industrial technology manufacturing company shaping solution that enable safe and efficient electrical energy transfer, expands its solid-state switching portfolio with SCD and SCP Series solid-state contactors for reliable control in single- and three-phase heating and motor applications.
As the global shift toward electrification drives demand for more reliable and efficient power control solutions, the SCD and SCP Series solid-state contactors help manufacturers improve system performance while reducing maintenance requirements and unplanned downtime. By eliminating mechanical wear and using advanced zero-cross switching technology, the devices minimize electrical noise and voltage transients for long-term reliability in demanding industrial applications. Their integrated design simplifies installation, supports compliance with global safety standards, and helps customers lower total cost of ownership.
The expanded solid-state contactor offering is available in eight configurations plus added accessories:
- SCD1-NR Series: One-pole switching, high endurance DIN-rail mount
- SCD1-CE Series: One-pole switching, essential DIN-rail mount
- SCP1-CE Series: One-pole switching, essential panel mount
- SCD2-CE Series: Two-pole switching, classic DIN-rail mount
- SCP2-CE Series: Two-pole switching, classic panel mount
- SCD3-CC Series: Three-pole switching, classic DIN-rail mount
- SCP3-CC Series: Three-pole switching, classic panel mount
- SCP3-CC…R Series: Reverser, panel mount
“As electrification accelerates across industrial environments, customers need power control solutions that deliver efficiency without compromising reliability,” said Hugo Neri, Global Product Manager of Industrial Solid-State Relays at Littelfuse. “The SCD and SCP Series solid-state contactors help machine builders address critical design considerations, including panel space, thermal performance, and long-term durability. With integrated heatsinking, flexible mounting options, and robust semiconductor technology, they simplify implementation in demanding heating and motor control applications.”
Typical applications for these products include:
- Industrial ovens: reflow/wave soldering, drying, curing, tempering, environmental test chambers
- Industrial packaging equipment: shrink tunnels, filling and sealing machines
- Industrial plastic processing equipment: injection molding, thermoforming, extrusion
Through this expanded offering, Littelfuse reinforces its commitment to solid-state technology solutions. These single- and three-phase contactors expand the existing Littelfuse portfolio of panel mount, DIN-rail mount, PCB-mount, and HVAC solid-state switching solutions.
