Mounting is via screw fixing or snap-on DIN rail, so the panel layout can be either a pre-drilled backplate or a standard 35 mm rail. Three slots for compact load feeders are built into this infeed module, meaning a single 3RA6813-8AB can feed up to three SIRIUS motor starters or soft starters in a ganged assembly without additional busbar work. ## Motor duty rating and wire termination Tightening torque for the M3 screw terminals is specified at 6 to 8 N·m, and the stripped length for main contacts is 17 mm — both values are needed for a reliable, torque-controlled termination. ## Environmental and compliance profile Operates from -20 °C to +60 °C and survives storage and transport from -55 °C to +80 °C, which suits unheated warehouses and container shipping. Vibration resistance tested at 2 m/s² from 5.8 to 500 Hz with 15 mm displacement at lower frequencies, and shock resistance at 6 m/s² semi-sinusoidal — this meets the mechanical robustness expected in conveyor, pump, and compressor panels near rotating machinery. Pollution degree 3 per IEC 60947-1, meaning it is rated for conductive pollution environments typical of industrial control panels without conformal coating on the busbars.","metaTitle":"Siemens 3RA6813-8AB SIRIUS Infeed Left, 100A AC-3, 690V","metaDescription":"Siemens 3RA6813-8AB SIRIUS infeed left for compact load feeders. 100A AC-3 at 400V, 690V max, screw terminals up to 50 mm².
