The CR4395 series Current Sensing Relay provides a stable method for monitoring electrical current
The CR4395 series Current Sensing Relay provides a 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. 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. Applications:
- Monitor electrical heater elements
- Sense motor over/under loads
- Detect lamp burn-out
- Indicate phase loss
