Overview

The 3rd generation CEP7 solid state overload relays offer superior motor protection with advanced features like:

  • Selectable trip class and field-installable modules
  • A wide current adjustment range of 5:1
  • Robust, self-powered design with mechanical and electrical mounting
  • Self-sealed latching mechanism
  • Single- and three-phase compatibility in same device allows for reduction in inventory SKUs

The basic concept of utilizing Application Specific Integrated Circuits (ASICs) results in an affordable solid state overload relay. This kind of versatility and accuracy was simply not possible with traditional bimetallic or eutectic alloy electromechanical overload relays. The CEP7 offers dramatically lower energy requirements that save money and reduce panel space. Check out these advanced features.
