Siemens Fail-Safe Direct Starter 3RM1101-1AA04

The Siemens SIRIUS 3RM1101-1AA04 is a fail-safe direct-on-line AC semiconductor motor starter from the compact 3RM1 series. It is designed for the functional switching and safety-related disconnection of three-phase motors in automation and machine safety applications. The unit is rated for operational voltages of 48 to 500V AC at 50/60 Hz, with a control supply voltage of 24V DC. The current setting range is 0.1 to 0.5A, covering motor loads up to 0.06 kW at 230V, 0.12 kW at 400V, and 0.18 kW at 500V. It carries a safety integrity rating of SIL 3 and Performance Level e (Category 4) per IEC EN 60947-4-2, making it suitable for locally limited safety functions that require certified shutdown capability. Integrated electronic overload protection is included, eliminating the need for a separate overload relay. The unit features hybrid switching technology combining semiconductor and relay elements for energy-efficient operation. Connection is via screw terminals (main and control circuit). The device meets IP20 enclosure protection and operates within an ambient temperature range up to 40 degrees C for the rated current. Compliant with IEC, GB, and UL standards and listed for group installation applications. The 3RM1101-1AA04 ships in its original Siemens SIRIUS packaging with documentation. MPN 3RM1101-1AA04, internal lot reference 780847.
