The CR4395/the CR7310 Current Sensing Relays are designed to monitor current levels in AC conductors
The CR4395 and the CR7310 Current Sensing Relays are designed to monitor current levels in AC conductors, and provide a dry relay contact activation when the current rises above or falls below a user adjusted set point. The 4395 is for general applications, and the 7310 is UL listed for use as a component of ground fault systems.

Specify remote current transformer when ordering remote sensing relay applications. (7310 only)

When ordering any of the above relays, time on delay (.5 to 6 sec. or 2 to 25 sec.) must be specified.

 
Features
  • Variable trip point and time delay
  • Monitors currents from 10ma. to 60 AC Amps
  • Electrical isolation between circuits
  • Output relay rated up to 20 Amps
  • LED relay status indicator
  • Dead band prevents relay chatter
  • Calibrated dial standard
  • External current transformers available
