Interface for operator panel:
Enables connection of the 3RA6935‑0A operator panel (optional accessory).
Rotary switches for rated operational current and trip class:
With the two rotary switches, you set the overload relay to the rated operational current of the
motor and the required trip class depending on the startup conditions.
Connecting terminals (removable joint block):
The generously dimensioned terminals permit connection of two conductors with different cross-
sections for the auxiliary circuits, control circuits, and sensor circuits. Connection is possible using
screw terminals or spring-loaded terminals.
Interface for current measuring module:
Enables the connection of a current measuring module (device required for system setup).
TEST/RESET button:
Enables self-testing of all important device components and device functions as well as resetting
of the device after a trip when manual RESET is selected.
Slide switch for AUTO/MAN‑RESET:
Enables selection between manual and automatic reset.
Automatic reset is only possible after overload tripping and thermistor tripping.
Red "OVERLOAD" LED:
A continuous red light signals an active overload trip; a flickering red light signals an imminent trip
(overload warning).
Red "THERMISTOR" LED:
A continuous red light signals an active thermistor trip.
