3RA1无熔断器负载馈线

3RA1 无熔断器负载馈线包括 3RV1 电机启动保护器和 3RT1 接触器。电机起动器保护器和接触器采用预装配的装配套件(接口模块、接线套件和标准安装导轨或母线适配器)进行电气和机械连接。由于3RA1无熔断器负载馈线是从 3RV1 电机启动保护器和 3RT1 接触器构造的，所以同样的附件也可像适用于这些电机启动保护器和接触器一样，用于 3RA 无熔断器负载馈线。预装配的装配套件可按适合*45 kW功率范围的附件供货。因此客户可快速、经济地装配所需无熔断器型负荷馈电器。和开关设备连用还可以节省时间，不像常规接线系统那样，不需要校正可能出现的接线错误。

3RV1 电机启动保护器负责无熔断器负载馈线中的过载和短路保护。备用保护设备(例如，熔断器或限制器)在这里是多余的，因为电机起动器保护器能够承受 400 V时*50或100 kA的短路。

3RT1 接触器*适合需要耐久部件的*其复杂开关任务。允许的环境温度为 60 °C，采用对接安装方式，无降额(70 °C 可能要受到一些限制条件的制约)。3RA1 无熔断器负载馈线可供用于 45 kW AC-3 和 400 V条件下的电机(接地网络)和 0.14 A 到 100 A的整定范围。

3RA2负载馈电器3RA2 无熔断器负载馈线包括 3RV2 电机起动保护器和 3RT2 机电式接触器。这些设备使用预组装的组装套件(链路模块、接线套件和标准安装导轨或者母排转接器)实现电气和机械连接。针对电流* 32 A(大约 15 kW/400 V)的标准感应电机的直接起动或可逆起动，可以订购这些* 3RT2 控制器与 3RV2 保护设备的大约 500 种预组装 3RA2 组合。在负荷馈电器 3RA2中，3RV2 电机起动器保护器负责过载和短路保护。此处，*需要后备保护设备，如熔断器或者限流器，因为该电动机起动器保护器在400 V时可**153 kA的短路。3RT2接触器*适用于要求*大耐久能力的、*其复杂的切换任务。

3RA6 无熔断器紧凑式起动器和用于 3RA6 的馈电系统集成功能 SIRIUS 3RA6 紧凑式起动器是一代*性负载馈电线，带有用于断路器、接触器和固态过载继电器的集成功能。另外，可选可安装附件的各种功能(如，辅助开关和浪涌抑制器)已经集成在 SIRIUS 紧凑式起动器。
