SDCS-FEP-2   2.2.3电子脱扣器的功能在以下页面中，报告了模制外壳和空气断路器的电子脱扣器的保护功能；关于不同释放的保护功能的可用性，应参考第43页的表格。这些页面中的示例显示了如何通过断路器前面的dip开关设置电子脱扣器；该操作也可以通过查看LED显示屏的控制装置（对于释放PR122-PR123-PR332-PR333）或通过测试装置PR 010T或SD-TESTBUS 2以电子方式执行。为了简化示例的阅读，未考虑保护功能的公差。对于正确的设置，有必要考虑与所用电子跳闸装置相关的不同保护功能相关的公差；有关此信息，请查阅技术目录。下图显示了配有电子脱扣器的断路器的时间-电流跳闸曲线，该电子脱扣器具有保护功能LSIG


SDCS-FEP-2  2.2.3 The functions of electronic releases In the following pages the protection functions of the electronic releases for both moulded-case as well as air circuit breakers are reported; as regards the availability of the protection functions with the different releases, reference shall be made to the table on page 43. The examples shown in these pages show how it is possible to set the electronic release by means of the dip-switch on the front of the circuit-breaker; this operation can be carried out also through the controls viewing the LED display (for the releases PR122-PR123-PR332-PR333) or electronically through the test unit PR 010T or with SD-TESTBUS 2. To simplify the reading of the examples, the tolerance of the protection functions has not been considered. For a correct setting it is necessary to take into consideration the tolerances relevant to the different protection functions referred to the electronic trip unit used; for this information please consult the technical catalogue. The figure below shows the time-current tripping curve of a circuit-breaker equipped with an electronic release having the protection functions LSIG which are described in the following pages:
