The Siemens 3RT1044 contactor from the SIRIUS 3RT1 series is a robust industrial switching device engineered for efficient motor control and power distribution. It is specifically designed for 30kW motors at 400V (AC-3 duty), making it suitable for medium-duty industrial applications such as pumps, compressors, conveyors, and HVAC systems.
With a rated operational current of approximately 65A, this contactor ensures reliable switching and long-term performance under frequent operating conditions.
The contactor features a 110V AC control coil, allowing smooth integration into standard control circuits. It is built as a 3-pole (3NO) configuration, with typical variants offering auxiliary contacts (2NO + 2NC) for enhanced control, interlocking, and signaling functions.
Constructed with Siemens SIRIUS technology, the device offers high mechanical durability and electrical endurance, ensuring reliable operation in demanding environments. The Size S3 compact frame enables easy installation in control panels with screw or spring-type terminals.
