What does relay action mean?
What is tuning current?
To answer
The setting current is the current you want to move. If the current relay current range is 20A ~ 40A, you can according to your needs to set the current to 25A, or 31A, to 25A, over-current relay normally closed contact disconnect, normally open contact closed, issued Flow signal, trip, or alarm. I just give an example, the specific setting range and value are readily written, see the specific product samples.
Relay action is to meet its operating conditions, the contact action, such as normally closed contact open, normally open contact closed. Such as time relay, when the coil was power (or loss of power) and the elapsed time to set the time, the contact action. Another example is the overcurrent relay, when the current flow through its setting current, the contact action normally closed contact open, normally open contact closed.
