Description

The SIEMENS - IEC Magnetic Contactor is a non-reversing, three-pole device with a coil voltage of 24V DC. It's designed for industrial applications and features an auxiliary contact configuration of 2NO/2NC. The contactor has a screw electrical connection and can be mounted on DIN rails or surfaces in a vertical position. With no enclosure, it carries an IP20 rating for protection against solid objects up to 12mm but not against liquids. This product belongs to the SIRIUS 3RT Safety Contactors series.

Key Features:

  • Non-Reversing Action: This product is designed for unidirectional operation.
  • Auxiliary Contact Form (2NC/2NO): Provides additional circuit flexibility by offering two normally closed and two normally open contacts.
  • Coil Voltage: Requires a coil voltage of 24V DC for activation of its switching mechanism.
  • Mounting Style: Can be mounted on DIN Rail or Surface, providing versatility in installation options.
  • Horsepower Ratings: Specifications vary based on phase and voltage, with a range from 2 hp at single phase-120V AC to 25 hp at three-phase-600V AC.
  • Maximum Operating Temperature: Rated for operation at temperatures up to 140 Degrees F.
  • Standards Compliance: Complies with REACH Art 33 and WEEE (2012/19/EU) standards ensuring responsible use of substances and electronic waste management respectively.
