The CR4395 Series, Current Sensing Relay provides an effec-
tive and highly stable method for monitoring electrical current.
The current-carrying wire is routed through the opening extend-
ing from the top of the case. When current reaches the level set
by the trip point adjustment, the relay trips and starts the ad-
justable timer. After the timer cycles the electromechanical relay
is energized. A precision voltage reference circuit ensures a
highly repeatable trip point.
