ОПИСАНИЕ ПРОДУКТА
SIEMENS 3RW4036-1BB14 - Soft Starter
This SIEMENS SIRIUS 3RW40 series soft starter is engineered for controlled ramp-up and ramp-down of three-phase asynchronous motors, mitigating mechanical shock and current peaks during start-up. It integrates two-phase control technology with an internal bypass contactor for reduced power dissipation after motor acceleration. This device is suitable for standard industrial applications requiring smooth motor operation, such as pumps, fans, conveyors, and mixers.
