西门子断路器 接触器 继电器 熔断器的介绍：
断路器：选用SIRIUS 3RV2电机起动保护器可节省约80%的设计时间80%机器和工厂的可用性是确保生产率的先决条件。长时间停机不仅成本昂贵，还可能还意味着开始失去客户的信任。应可靠保护机器和工厂免受电源系统的影响。发生故障时电机起动保护器可迅速断开设备与电源的连接，从而防止产生更昂贵的损坏。
接触器：使用SIRIUS接触器分断电机，可实现真正的应用灵活性。设备和附件的可扩展性以及连接技术的多样性，例如使用笼卡式技术进行简单的免工具和无误安装，将使您lingxian于竞争对手。SIRIUS接触器集成于各种工程及选型工具，支持您实现数组化转型。
继电器：西门子SIRIUS（国产）控制与保护产品3RT7系列2021年正式亮相。作为SIRIUS家族的新成员，3RT7致力于为客户创造更多的价值，提供更好的服务。3RT7系列控制与保护产品主要包括三大类产品，分别是3RT7接触器、3RU7热过载继电器、3RH7中间继电器。其中3RT7接触器电流规格是6-95A，3RU7 热过载继电器电流规格是0.11-100A、3RH7中间继电器本体有4个触点，上限多可以扩展到8个触点。
熔断器：3NE/3NC3系列gS/gR/aR半导体保护熔断器能快速分断短路电流，对于半导体器件和回路提供有效保护。广泛应用于变频器和软启动器以及循环回路。3NE/3NC熔断器提供对变频器及软起动的短路保护。所有用于变频机传动装置的电源类半导体器件，都需要快速分断来保护，3NE/3NC非常适合满足这类的应用要求。
