| 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. |
