106 A at 40 °C — the current that matters for motor starting
The 3RW3047-2BB04: That 106 A figure is the continuous motor current it can start and run — not a one-shot surge. It operates on 50/60 Hz supply (control voltage 24 V at both frequencies) and carries a 600 V insulation voltage rating. Pollution degree 3 per IEC 60947-4-2 means it's rated for industrial environments where conductive pollution is expected — no extra conformal coating needed for most panel conditions.
Mounting and wiring — DIN rail fit and terminal sizes
Mounts on DIN rail via screw and snap-on fastening. Dimensions are 70 mm wide, 170 mm high, 190 mm deep — that 190 mm depth is the dimension to watch when sizing the enclosure depth. Clearance requirements: 60 mm above, 40 mm below, 30 mm at the sides. Auxiliary contact terminals take 2x (24...14 AWG). The back and front clamping points each accept 10...2/0 AWG. Maximum motor cable length is 300 m — long enough for most pump and conveyor runs in a plant. The mounting position allows ±10° rotation and ±10° tilt front-to-back on a vertical surface.
Active production — sourcing posture
Sourced through authorized Siemens distribution. No second-source cross-reference — this is a single-source Siemens part number.
