1692 Block-Style Electronic Circuit Protectors

Our Bulletin 1692 Electronic Circuit Protection Modules protect the secondary circuits of 24V DC switched mode power supplies. These modules monitor both supply voltage and load currents, and you can monitor and control the modules both locally and remotely.


  • Allows less "let-through" energy than non-limiting circuit breakers
  • Uses output circuit indicators to indicate the presence of affected circuits for rapid troubleshooting and correction
  • Provides ON/OFF and reset buttons
  • Offers certified Class 2 circuits (on select devices only)
  • DIN Rail mountable
