Non-Reversing Solid State Contactors

Non-reversing contactors are designed for both resistive and inductive loads, and are an ideal choice to control everything from heating elements and lamps to motors and transformers. Another type of non-reversing contactor provides peak performance for demanding motor starts and is designed specifically for direct-on-line (DOL) starting of 3-phase motors, which transcends the limitations of traditional electromechanical contactors, particularly where frequent starting, stopping, jogging, or plugging are essential.

Advantages of solid state non-reversing contactors:

  • Near-Infinite Lifespan: No mechanical wear, arcing, and contact degradation inherent in traditional contactors, which ensures continuous operation and maintenance and replacement costs savings for applications such as cranes, conveyors, and other heavy industrial machinery
  • Simplicity and Cost-effectiveness: A non-reversing contactor is a simple device that is less expensive to purchase, install, and maintain than more advanced options
  • Application Requirements: If your equipment, such as a fan, pump, or conveyor system, is designed to operate in only one direction, then a non-reversing contactor is the most efficient and logical solution
  • Robust & Compact Design: These contactors are built for durability in harsh industrial environments and offer a compact, DIN rail mountable design, saving valuable panel space and simplifying installation
