Description

The Siemens IEC Magnetic Contactor is a 3-pole, non-reversing electrical switch rated for operation within IEC standards. It features a 24 V DC coil, screw terminals, and 2NO/2NC auxiliary contacts (4 contacts total). The device uses Frame B with Frame Size S0 and can be mounted on a DIN rail or surface. It does not include an enclosure; suitable for use in environments meeting IP20 requirements. It has an IP20 rating, supports up to 690V AC, and rated for operation within three-phase electrical systems as specified. A permanently mounted auxiliary contact is included, and the product is part of the SIRIUS 3RT Safety Contactors series, with REACH Art 33 and WEEE standards noted. The unit is rated for a maximum continuous load of 12 A (inductive) and 40 A (resistive) at specified voltages, with a maximum operating temperature of 140°F and minimum of -13°F. It specifies typical power dissipation under normal operating conditions; actual values depend on usage parameters. It is designed for a vertical mounting position with dimensions of 1.77 in wide and 6.3 in tall, and a depth of 4.21 in.

Action: Non-Reversing — indicates non-reversing configuration only, no guarantee of reversing functionality
