3VA molded case circuit breakers
398 Manual, 04/2015, A5E03603177010-02
The TD500 mobile test device can be used to test the different causes of ETU trips. It is
therefore useful for checking the proper functioning and correct wiring of all connected
system components before the 3VA2 molded case circuit breaker is commissioned. The
system behaves as it would in the case of a real trip event. The molded case circuit breaker
trips when the set delay times expire and signals all alarms and tripped signals from
connected components.
Benefits of the TD500 test device
● A TD500 test device via powerconfig can be used to successively parameterize all 3VA2
molded case circuit breakers directly in situ.
● The device can store up to 100 test results.
● Using the TD500 test device and the powerconfig software, it is possible to read out all
diagnostic data of the 3VA2 molded case circuit breaker either digitally or as a hardcopy.
● In addition, test functions can be performed directly on the PC with the powerconfig
software.
