Test function for the 3RB30/3RB31 solid-state overload relay
The correct function of the relay when ready for operation can be checked by pressing the
TEST button with the motor current flowing (device/electronics test). Current sensing, the
motor model, and the tripping unit are tested.
The switch position indicator slide can be used to test the auxiliary contacts and the control
current wiring. The tripping of the relay can be simulated by moving the slide, thereby
providing a means of checking that the auxiliary circuit has been wired correctly.
