Active production — PE infeed for SIRIUS starters
The Siemens 3RA6860-6AB is a PE infeed module in the SIRIUS family, designed to supply the protective earth (PE) bus to a motor starter assembly. It is rated for 63 A operational current at 400 V AC, making it suitable for feeding the PE rail in a group of SIRIUS starters up to that current ceiling.
Terminal capacity and wiring
The stripped length is 13 mm, and the recommended tightening torque is 3 to 4.5 N·m with an M3 screw.
Panel fit and environmental limits
The module measures 32 mm wide, 65 mm high, and 70 mm deep, and uses plug-in fixing to snap onto a DIN rail. It operates from -20 to +60 °C and can be stored or transported from -55 to +80 °C. Installation altitude is limited to 2000 m above sea level.
