Page 44: Electronic Trip Unit Etu
Description 2.9 Electronic trip unit ETU Electronic trip unit ETU As a protection device, the circuit breaker has the task of protecting installations and clearing electrical faults occurring in the system.

Selectivity tables for the 3WL10 are available on the Internet for simple implementation of selective trip combinations (see Selectivity tables (https:// support.industry.siemens.com/cs/ww/en/view/109748621)). The parameters relevant to selectivity are: • Tripping value settings of the trip unit • Tripping and break times •...
Page 48 Description 2.9 Electronic trip unit ETU The selective behavior of circuit breakers can be implemented technically by a variety of selectivity concepts: • Current selectivity The selectivity can be calculated in the overload range by comparing the time/current characteristics. In the short-circuit range, this comparison leads to values that are too low. The reason for this is that the trip unit behaves differently in the case of short-circuit currents compared to its long-term behavior, e.g.
Page 49: Design Of The Electronic Trip Units
Description 2.9 Electronic trip unit ETU This makes the power distribution system totally selective. Siemens protection devices are designed for optimum coordination in order to achieve just that.

The contact system will now stay together with this energy to be able to withstand substantial short-circuits (I value of an air circuit breaker).
Page 186: Entering Parameters
Software: powerconfig powerconfig is a commissioning and maintenance software for all communication-capable SENTRON products from Siemens. With this software, the circuit breaker can be parameterized, commissioned and its settings can be archived and, in the operating phase, values from the installation (current, voltage, etc.) read out and the status of the circuit breaker can be acquired.
Page 187 Operation 6.1 Operation Setting parameters with the rotary coding switch 1. Select the rotary coding switch of the protection release for which you want to set or modify the parameters. 2. Turn the arrow of the rotary coding switch to the required parameter value using a suitable screwdriver.
