Why upgrade or migrate to CEP7-1 Electronic Overload Relay

While the CEP7-ED1/EE Overload Relay has been a valuable part of NHP’s Motor Protection Portfolio for over 18 years, this product is now obsolete and superseded by the Sprecher + Schuh CEP7-1 Electronic Overload Relay. The CEP7-1 is the next generation electronic overload relay. It has enhanced features to better safeguard your motor investments, including increased accuracy and repeatability, a self-powered design with lower heat dissipation, and optional expansion capabilities.

NHP understands that your overload relays are a critical asset in your motor control system, and we support that by providing you with the latest technology to maximise your investment. New technologies can improve and extend the operation of existing equipment and provide an immediate boost to productivity. By migrating from your legacy Sprecher + Schuh CEP7-ED1/EE Overload to a new CEP7-1 Electronic Overload Relay, you can help to decrease downtime, increase speed to market, and optimise operations well into the future.

  • Identical mounting footprint to CEP7 for direct mount configurations with CA7 contactors
  • Equivalent overload performance, features and wiring as compared to 2nd gen CEP7
