It is designed for three-phase supply voltages from 200 to 480 V AC and accepts a control\/auxiliary voltage of 110–230 V AC\/DC. The unit uses thyristor-based soft starting with an integrated bypass contact system to reduce heating and losses after start-up, and it is specified for operation on 50–60 Hz networks. \u003c\/p\u003e \u003cp\u003e Typical motor compatibility covers small industrial motors in the 1.5–3 kW range (depending on system voltage and ambient temperature). This model is appropriate for straightforward industrial motor starting tasks such as small pumps, fans, compressors and conveyors where simple soft-start functionality and compact footprint are required. Notable verified features for this SKU include the integrated bypass contact system and thyristor power stage. The device does not provide intrinsic motor overload protection; external overload or motor protection must be used where required by the application. \u003c\/p\u003e \u003cp\u003e Practical notes for procurement and installation: the rated operational current falls with increased ambient temperature (manufacturer ratings specify 6 A at 50 °C and 5.5 A at 60 °C), so select the correct size when ambient conditions or duty cycle impose additional thermal stress. The 3RW3014-1BB14 is intended as a low-cost, easy-to-commission soft starter for engineers and maintenance teams who need controlled starting current and reduced mechanical shock without advanced communication or integrated motor protection. \u003c\/p\u003e\n\u003c\/section\u003e \u003csection id=\"technical-attributes\"\u003e \u003ch3\u003eKey Soft Starter Attributes\u003c\/h3\u003e \u003ctable\u003e \u003ctbody\u003e \u003ctr\u003e \u003cth\u003eRated operational current (Ie)\u003c\/th\u003e \u003ctd\u003e6.5 A (at 40 °C); 6 A (at 50 °C); 5.5 A (at 60 °C)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth\u003eMotor power range\u003c\/th\u003e \u003ctd\u003e3 kW at 400 V (standard circuit); 1.5 kW at 230 V (standard circuit)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth\u003eSupply voltage\u003c\/th\u003e \u003ctd\u003e200–480 V AC\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth\u003eControl \/ auxiliary voltage\u003c\/th\u003e \u003ctd\u003e110–230 V AC\/DC\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth\u003eBuilt-in bypass\u003c\/th\u003e \u003ctd\u003eYes (integrated bypass contact system)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth\u003eMotor protection functions\u003c\/th\u003e \u003ctd\u003eNo intrinsic motor overload protection (external protection required)\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Default Title","offer_id":51636637434139,"sku":"3RW3014-1BB14","price":154.47,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/siemens-3rw3014-1bb14-3rw30-to-480v-ac_6fcdf10b-7e5d-47d2-8e90-fa9e9e684828.jpg?v=1777185592"},{"product_id":"siemens-3rw3016-1bb14-soft-starter-4-kw-9-a-200-to-480v-ac","title":"3RW3016-1BB14,  Soft Starter, 4 kW, 9 A, 200 to 480V AC","description":"\u003cdiv\u003e\n\u003csection id=\"series-overview\"\u003e \u003ch2\u003eSiemens 3RW30 Soft Starter Series – Overview\u003c\/h2\u003e \u003cp\u003e Siemens 3RW30 soft starters are compact and cost-effective motor starting solutions designed for basic soft starting of three-phase asynchronous motors in standard industrial applications.

The unit accepts a control supply of 110–230 V AC\/DC and is designed for ambient temperatures up to 40 °C without derating. Typical applications include single-direction starting of small pumps, fans, compressors and conveyor drives where limiting inrush current and reducing mechanical stress are primary requirements.
