Siemens Power Contactor 3RT20231AP00 AC-3 4kW 9A 230V 50Hz 1NO 1NC Size S0
The Siemens power contactor is an industrial-grade switching device engineered for reliable motor control and power distribution applications. As part of the modular SIRIUS system, this 3-pole contactor delivers dependable performance with high contact reliability in a space-saving housing. It is designed to handle demanding electrical switching tasks efficiently while integrating smoothly into automated systems.
This power contactor features a compact design that saves valuable space within control cabinets while maintaining high operational reliability. Integrated auxiliary switches help reduce overall design complexity, and front-panel screw terminals simplify the wiring process during installation. The device is climate-resistant, approved for international use according to major standards, and ready for modern high-efficiency motor categories. Its modular construction allows seamless combination with other SIRIUS components to build optimized load feeders.
This device is not designed for direct residential use without appropriate enclosure and professional electrical installation. It is also unsuitable for DC control voltage applications since its coil is specifically rated for 230V AC at 50Hz.
Installation should be performed by qualified electrical personnel in accordance with relevant safety standards. Mount the contactor securely onto a standard mounting rail inside a suitable control cabinet. Connect the main power lines and the 230V 50Hz AC control supply to the designated screw terminals, ensuring all connections are properly torqued. Integrate the built-in auxiliary contacts into your control circuit as needed for signaling or interlocking purposes before energizing the system.
Operate the device within its specified electrical and environmental ratings, and periodically inspect screw terminal connections to maintain optimal performance and safety in industrial environments.
