Description

The SIEMENS - IEC Magnetic Contactor is a non-reversing, three-pole device rated for operation within the specified voltage ranges of 24V DC. It features an auxiliary contact configuration of 1NO/1NC and is compatible with both DIN Rail and Surface mounting styles. The product comes from the SIRIUS 3RT20 series and carries an IP rating of IP20. With its frame size labeled as S0, this magnetic contactor is rated for operation with inductive loads up to 17A and resistive loads up to 40A.

Key Features:

  • Auxiliary Contact Form: This feature allows for one normally open (NO) and one normally closed (NC) auxiliary contacts.
  • Coil Voltage: Rated for operation within the specified voltage ranges of 24V DC.
  • Mounting Style: Compatible with both DIN Rail and Surface mounting styles.
  • Full Load Amps: Rated for operation with inductive loads up to 17A and resistive loads up to 40A.
  • Horsepower Ratings: Horsepower ratings are dependent on phase and voltage, ranging from single-phase at 120V AC producing an output of approximately 1 hp, through to three-phase at 600V AC producing an estimated maximum output of around15 hp.
  • Maximum Operating Temperature & Minimum Operating Temperature: Designed for use within a temperature range between -13 Degrees F (-25°C) and140 Degrees F (60°C).
  • Standards Compliance: Complies with REACH Art33 standards along with WEEE(2012/19/EU).
