The 3RT6028-1AC20 is part of the Siemens SIRIUS modular system, allowing seamless integration with other components such as overload relays, circuit breakers, and PLCs. It is commonly used in motor control centers, conveyor systems, pumps, fans, and compressors. With its high switching capacity and robust construction, it ensures dependable performance in harsh industrial environments. The Siemens 3RT6028-1AC20 is a 3-pole contactor from the SIRIUS 3RT6 series, designed for reliable switching of motors and other loads in industrial automation systems. Basic Product Information Coil voltage 230V AC 50/60Hz Integrated 1 NO + 1 NC auxiliary contact Compact design for space-saving installation Screw terminals for reliable wiring High mechanical and electrical endurance Complies with international standards (IEC, UL, CSA) 3-pole contactor with rated current 32A (AC-3) at 400V Technical Specifications Version & Model Difference The Siemens 3RT6 series includes various versions differing by coil voltage (AC/DC), auxiliary contact configuration, and rated current. The 3RT6028-1AC20 specifically has a 230V AC coil and 1 NO + 1 NC auxiliary contacts. Other versions may have DC coils (e.g., -1BB20 with 24V DC) or different auxiliary contact arrangements. The 3RT6 series also offers variants with electronic coil interface for PLC control and versions with higher breaking capacity for specific applications. Application Scenarios What is the coil voltage of this contactor? The coil voltage is 230V AC 50/60Hz. Ensure your control circuit provides this voltage to energize the contactor. Does the 3RT6028-1AC20 come with auxiliary contacts? Yes, it is equipped with one normally open (NO) and one normally closed (NC) auxiliary contact, which can be used for feedback or interlocking circuits. Can this contactor be used with Siemens overload relays? Yes, it is compatible with Siemens SIRIUS 3RU2 overload relays. They can be mounted directly on the contactor for motor protection. What is the rated current of the Siemens 3RT6028-1AC20 contactor? The rated operational current is 32A in AC-3 duty at 400V. This makes it suitable for controlling motors up to 15kW at 400V.
