The main circuit uses screw-type terminals, accepting solid conductors up to 2x (0.5...1.5 mm²) or 2x (0.75...2.5 mm²) and stranded up to 2x (10...50 mm²). That covers most panel wiring from control to power feeds. AC-3 at 1000 operations per hour is the mechanical switching rate for motor starting — the contactor can cycle a motor on and off every 3.6 seconds without overheating the coil or arc chamber. AC-4 (inching/plugging) is limited to 300 ops/h because the make-and-break under stalled-rotor current stresses the contacts harder. The coil hold range at 50 Hz is 0.8...1.1 x rated voltage, at 60 Hz 0.85...1.1 x rated voltage. That means a 24 V coil stays pulled in down to about 19.2 V at 50 Hz, which matters when the control transformer sags under load. No special tooling or firmware versioning to track. Dimensions: 146 mm high, 70 mm wide, 139 mm deep. IP20 on the front with cover or box terminal; the terminal body itself is IP00. In a panel with a closed door, the front IP20 is fine. For open-panel maintenance, keep hands clear of the live terminals. No additional conformal coating required for normal factory-floor environments.","metaTitle":"Siemens 3RT1044-1AG60 SIRIUS Power Contactor, S3, 37 kW at 5","metaDescription":"Siemens 3RT1044-1AG60 SIRIUS power contactor, size S3, rated 37 kW at 500 V AC-3.

The 3RT1044-1AG60 uses screw-type terminals; the -1FB46 variant uses a different coil voltage. They share the same footprint and rail mounting, so a panel swap is possible if the coil voltage matches, but verify the terminal wiring range."},{"question":"What is 3RT1044-1AG60's listed depth (139 mm) on this component line?","answer":"The depth is 139 mm, which includes the contactor body and screw-terminal projection. Allow extra space for wiring bend radius inside the enclosure."},{"question":"What compliance documentation does this brand provide for 3RT1044-1AG60 (RoHS, REACH, UL, IEC)?","answer":"The product is a Siemens SIRIUS power contactor designed to IEC/EN 60947-4-1 standards. Compliance documentation (RoHS, REACH, UL file) is available from Siemens upon request; the part carries CE marking for the European market."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT1044-1AG60","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RT1044-1AG60 when reusing this data.
