9.4 Breaker Data Adapter
9.4.1 Application
The Breaker Data Adapter (BDA) makes it possible to parameterize, operate and monitor the circuit breaker without additional software by
means of a browser-capable input/output device (e.g. a laptop). This is possible for circuit breakers equipped with trip units of the types
ETU745 - 776. On trip units ETU745 and ETU748, however, the basic protective functions cannot be parameterized. These are adjusted
solely by using the rotary coding switches.
Communication with the electronic system of the circuit breaker takes place via the c. For this purpose, the BDA can be option-
ally connected to the test socket of the trip unit, or - in case of longer stationary operation - to the last cmodule, and snapped onto
a 35-mm DIN rail. The required connection cables are supplied with the unit.
