6RY1801-0AA01 Siemens 24V Axial-flow Fan 0.27A 6.5W Ebmpapst 3214J/2N

1.Overview of the 6RY1801-0AA01 Siemens

The 6RY1801-0AA01 is the basic model of the electrically operated miniature circuit breaker (MCB) in the Siemens SIRIUS low-voltage electrical appliance family. Designed for 230 V/400 V power distribution systems, it provides overload and short-circuit protection and offers optional remote electric closing/opening functionality. Its modular design allows for direct insertion into SIRIUS 3R series control cabinets and is also compatible with third-party busbar systems, making it a "safety keeper" for industrial power distribution, motor feeders, and building lighting panels.
