Note
On the circuit breaker, the connection from the ETU to the trip coil and its ability to function
can only be electromechanically tested after a fault, maintenance, or modification of the
device. The electronics of the instrument transformers via ETU to the trip coils are
continuously monitored during operation to ensure the greatest safety and faults are handled
immediately (tripping or only alarm).

TD310 Activation & Trip Box
The TD310 Activation & Trip Box is connected to the front test plug of the ETU. It can be
used with all electronic trip units of the 3- and 6-series.
Function scope:
●
Activation of the electronic trip units of the 3- and 6-series with a battery built into the test
device
●
Testing the release and the trip coil of the circuit breaker for correct functioning (trip test)
●
By activation via the TD310 Activation & Trip Box, the electronic trip units of the 6-series
can be parameterized on the display, even when the circuit breaker is switched off.
Note
With or without an external power supply, the reasons for the last trip are always displayed
on the LEDs (ETUs of the 3-series) or on the display (ETUs of the 6-series) when the control
key "i / Test" is pressed. To enable this display, the ETU has a battery.
