Information About 3RT1044-1BB40
The 3RT1044-1BB40 contactor from Siemens is part of the SIRIUS 3RT1 series, optimized for switching motors and high-current loads in industrial environments. This model supports AC-3 motor loads up to 30 kW at 400 V and handles continuous currents of up to 65 A. With a 24 VDC control voltage, it ensures fast and reliable operation in automation panels. The contactor features a 3-pole non-reversing configuration and uses screw terminals for stable mechanical and electrical connection. Its S3 size format allows it to fit standard enclosure spaces while maintaining robust thermal and electrical endurance. Widely used in motor starters, control panels, and power distribution assemblies, it meets international industrial standards for reliability and safety.
Key Features:
- AC-3 Rated for 30 kW at 400 V: Supports direct-on-line motor starting and switching under full load.
- 65 A Current Rating: Handles high inrush and running currents, suitable for medium-to-heavy duty motor applications.
- 24 VDC Coil Voltage: Enables fast and energy-efficient coil operation with low control voltage.
- 3-Pole Configuration: Standard design for balanced 3-phase motor switching.
- S3 Frame Size: Fits Siemens’ standardized panel layouts, offering compact design with high capacity.
- Screw Terminal Connection: Ensures reliable wire retention and resistance to vibration.
- Non-Reversing Design: Ideal for applications requiring straightforward motor control without directional change.
- Thermal and Electrical Endurance: Engineered for long service life under frequent switching conditions.
- Industrial Grade Build: Made for tough environments with consistent mechanical performance.
The 3RT1044-1BB40 offers efficient, durable switching for motors and industrial loads, combining compact design with reliable performance and international compliance.
