S00 frame, 45 mm wide — panel fit for dense DIN rails
The 3RT6016-1BM41: This is a Size S00 contactor, the smallest frame in the Siemens SIRIUS line, at 45 mm wide and 57.5 mm tall. Depth is 73 mm, so budget that behind the panel door.
Motor ratings that actually govern the selection
At 400 V AC-3e duty — the standard motor-switching category — this contactor is rated 13 kW at 60 °C ambient. That is the number that decides the motor FLC it can handle in continuous operation. At 230 V it is rated 7.5 kW, and at 690 V it reaches 22 kW, all at 60 °C. Auxiliary contacts are available as a bolt-on extension — the product accepts an auxiliary switch block. The control circuit uses screw-type terminals, same as the main circuit.
Current production — no lifecycle worry
The SIRIUS 3RT family is the standard IEC contactor line for panel builders and OEMs.
Terminal specs and wire range
AWG equivalents are 2x (20 to 16), 2x (18 to 14), and 2x 12. Minimum permissible cross-section at 40 °C is 4 mm²; at 60 °C it drops to 2.5 mm² — the higher ambient derates the conductor ampacity.
Environmental and compliance baseline
Substance prohibitance date is 05/01/2012, aligning with RoHS compliance.
