Description

The Siemens IEC Magnetic Contactor is a 3-pole, reversing, electrically operated switch designed to control power circuits in line with IEC standards. It uses a 24 V DC coil with screw terminals and is part of the SIRIUS 3RA23 series (frame size S0). The device features three main normally open contacts (3 NO) and no normally closed main contacts (0 NC), plus three auxiliary contacts configured as 2 NO / 2 NC. It is rated for operation within the specified voltage range of up to 690 V AC, with IP20 protection and no enclosure, and designed for vertical mounting on DIN rail or surface in accordance with installation guidelines. A mechanical interlock is included, and it is suitable for three-phase systems, with operating temperatures from -13°F to 140°F and has a mechanical lifespan rating based on standard testing procedures.
