6SL3330-7TE33-8AA3

The Siemens 6SL3330-7TE33-8AA3 Active Line Module is a high-performance component designed for seamless integration into industrial drive systems. Engineered to operate with a line voltage of 3 AC 380 to 480 V, this module is capable of delivering rated power for DC operations at both 50 Hz 400 V and 60 Hz 460 V, with respective outputs of 235 kW and 300 hp for standard rated current, and 210 kW and 250 hp for base-load current.

This robust module boasts a DC-link current with a rated current of 425 A and a maximum current of 637 A, ensuring reliable performance even under demanding conditions. The infeed/regenerative feedback current features a rated current of 380 A and a maximum current of 570 A, providing efficient energy exchange within the system.

The unit is equipped with a 24 V DC auxiliary power supply drawing 1.4 A and a 400 V AC drawing 1.8 A, alongside a DC link capacitance of 7,800 µF, which can be expanded up to 76,800 µF for larger drive line-ups. The maximum power loss is capped at 3.90 kW for 50 Hz 400 V and 4.20 kW for 60 Hz 460 V, indicative of its efficiency.

Connection-wise, the module features a line connection with a flat connector design for M10 screws and allows for a maximum conductor cross-section of 2 x 240 mm² according to IEC standards. The same design and capacity apply to the DC link, PE, and PE2/GND connections, ensuring a secure and reliable electrical interface.

With an IP20 degree of protection, the module is built for indoor use and has a weight of 136 kg. Its dimensions are optimised for industrial environments, with a width of 326 mm, a height of 1,533 mm, and a depth of 545 mm. The cooling air requirement is 0.36 m³/s, and the sound pressure level is maintained at 69 dB for 50 Hz and 73 dB for 60 Hz operations.

The module is designed to handle a minimum short-circuit current of 10,500 A and supports maximum line lengths of 2,700 m for shielded cables and 4,050 m for unshielded cables, providing flexibility in system design and layout.

The Siemens 6SL3330-7TE33-8AA3 Active Line Module is a testament to advanced engineering and is suitable for a wide range of industrial applications where reliable power infeed and conditioning are critical for operational success.
