CR4395 Series Current Sensing Relays

CR Magnetics provides an effective method for monitoring electrical current

Image of CR Magnetics' CR4395 Series Current Sensing Relays CR Magnetics' CR4395 series current sensing relays provides an effective and highly stable method for monitoring electrical current. The current-carrying wire is routed through the opening extending from the top of the case. When current reaches the level set by the trip point adjustment, the relay trips and starts the adjustable timer. After the timer cycles, the electromechanical relay is energized. A precision voltage reference circuit ensures a highly repeatable trip point. The design of the power-on delay circuitry allows the supply power to be repeatedly cycled on and off without affecting the stability of the current sensing operation.

Features
  • Variable trip point and time delay
  • Monitors currents from 1 A to 100 A, AC
  • Electrical isolation between circuits
  • Output relay rated up to 20 A
  • LED trip status indicator
  • Dead band prevents relay chatter
  • Calibrated dial option available
  • External current transformers available
Applications
  • Monitor electrical heater elements
  • Sense motor over/under loads
  • Detect lamp burnout
  • Indicate phase loss
