What is the return current of the current relay?
To return to position
So there is a return (release) current
Also called release current
Current relay return current, that is, when the current is lower than that value when the current relay is no longer sucked in. This current is called the current relay return current.
[Current relay return current] For the current relay, when the starting current reaches a certain value, the coil starts the magnetic force is greater than the spring force and the inherent mechanical resistance, contact action connected, then the current called the starting current. After starting, when the current drops to a certain value, the coil starts the magnetic force plus the inherent mechanical resistance less than the spring force, the relay contact action is disconnected, when the current is called the return current. In the relay protection, in order to ensure the reliability of the relay, the starting current and return the ratio of the ratio of different requirements.
