Description

The Siemens IEC Magnetic Contactor is a 3-pole, non-reversing, electrically operated switch used to control power circuits. It is energized by a 24 V DC coil and includes one normally open auxiliary contact. The device uses screw terminals and is part of the SIRIUS 3RT20 family (frame S00) with no enclosure, rated for operation within IEC-standard voltage and current ranges.

Coil voltage: rated for specified coil voltage (e.g., 24 V DC)

  • Compatible with series specifications as per manufacturer data
  • Electrical connection: designed for screw terminal connections within specified parameters
  • IP rating: IP20; Enclosure: No enclosure
  • Maximum operational voltage: up to 690 V AC
  • Full-load current rating: inductive 16 A; resistive 22 A
  • Power dissipation: as per datasheet (typical operating conditions)
  • Maximum operating watts: as per testing standards and specifications (e.g., 8 kW at 400 V AC-3; 13 kW at 400 V AC-1)
  • Mechanical durability: 30,000,000 cycles (durability rating indicates expected mechanical lifespan and is not a guarantee for all cycles)
  • Operating temperature range: -13°F to 140°F (rated for safe and reliable operation within this range)
  • Mounting style: DIN rail or surface mounting; Mounting hole diameter: 0.20 in
  • Mounting hole distance (height/width): 1.97 in / 1.38 in
  • Overall dimensions (H x W x D): 1.95 in × 2.40 in × 3.30 in
  • Phase: Three; Standards: REACH Art 33, WEEE
  • NEMA Enclosure Rating: No enclosure
