1 Connection for contactor mounting:
In terms of their electrical and mechanical features and their design, these pins are perfectly compatible
with the 3RT2 contactors for the direct mounting of overload relays with screw-type or spring-loaded
terminals. Stand-alone assembly is also an option in conjunction with a stand-alone assembly module
(accessory).
2 Threshold value for current overshoot:
The rotary knob is used to set a threshold value for current overshoot. Setting the button to "OFF"
deactivates this function.
3 Threshold value for current undershoot:
The rotary knob is used to set a threshold value for current undershoot. Setting the button to "OFF"
deactivates this function.
4 Slide switch to select manual/automatic RESET with RESET function:
The slide switch is used to choose between manual and automatic RESET. The device can be reset by
switching between manual and automatic RESET.
5 Control circuit terminal (removable):
The control circuit can be connected using either the screw-type or the spring-loaded connection system.
6 Main circuit terminal:
The main circuit can be connected using either the screw-type or the spring-loaded connection system.

8 Device order number
9 ON-delay time "onDel (s)":
The rotary knob is used to set the ON-delay time. Monitoring for current overshoots and undershoots
starts when the relay detects current flow once this time has elapsed. Cable break/phase failure
monitoring is always active.
10 Delay time "Del (s)":
The rotary knob is used to set the delay time. Once this time has elapsed, the output relay will switch to
the fault condition if the current is overshot or undershot. Cable break/phase failure monitoring is active
immediately.
11 Status display via LEDs "Ready" for auxiliary voltage and "Fault" for the switching state
