The mechanism is sized for S2-frame circuit-breakers — that's the physical interface. Mounting is by screw fixing in any position, with zero clearance required upwards, forwards, backwards, downwards, and at the sides. That means it fits tight in a panel without needing breathing gaps around the mechanism body. The 224 mm height, 148 mm width, and 211 mm depth define the envelope; verify your enclosure door clearance and DIN-rail backplane layout against those numbers. Operating frequency is capped at 25 operations per hour — that's the mechanical limit for the motorized drive. Not a part for high-cycle jogging; it's for occasional remote switching of the breaker, say for emergency stop reset or remote disconnect. Shock resistance is rated at 25g / 11 ms, so it survives handling and moderate vibration in the panel. The part carries a substance prohibitance date of 03/01/2017 (RoHS / REACH compliance cutoff).","metaTitle":"Siemens 3RV1936-3AB4 SIRIUS Motor Remote Operating Mechanism","metaDescription":"Siemens SIRIUS 3RV1936-3AB4 motor remote operating mechanism for S2 circuit-breakers, 24 V DC.

The 3RT1044-1FB46 has a 70 mm width and 163 mm height versus the 3RV1936-3AB4's 148 mm width and 224 mm height, so it will not drop into the same panel footprint or mounting interface without rewiring and re-drilling."},{"question":"What compliance documentation does Siemens provide for 3RV1936-3AB4?","answer":"The part carries a substance prohibitance date of 03/01/2017, indicating RoHS and REACH compliance documentation is available from Siemens for this order code."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RV1936-3AB4","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/3RV1936-3AB4 when reusing this data.
