6SL3310-1TE33-1AA3

The Siemens 6SL3310-1TE33-1AA3 serves as a robust converter power module within the SINAMICS S120 series. This unit is capable of working with a line voltage spanning from 342 V to 528 V AC and is engineered for three-phase applications. With a rated output current of 310 A, it ensures effective current delivery to connected systems. The device also requires 0.9 A of current from a 24 V DC auxiliary power source.

Designed to handle operational frequencies of up to 2 kHz, the 6SL3310-1TE33-1AA3 experiences a power loss of 4 kW when operating at 50 Hz with a 400 V supply. Proper cooling is enabled through the module’s requirement for 0.36 m³/s of cooling air. In terms of noise management, this unit has a sound pressure level that reaches 69 dB at 50 Hz and 73 dB at 60 Hz, which could be important for noise-sensitive environments.

This model is built with a minimum short-circuit current capability of 4,400 A, enhancing its safety in case of operational faults. Encased with an IP20 degree of protection, it is designed for indoor use, shielding the internals from dust and larger objects but not from water exposure. The module is fairly substantial with a weight of 162 kg (357.15 lb) and is housed in a GX frame size. It permits the connection of conductors with a maximum cross-section of 2 x 240 mm², utilizing an M10 screw for motor connections.

In terms of dimensions, the converter has a width of 326 mm (12.8 inches), a height of 1,533 mm (60.35 inches), and a depth of 549 mm (21.61 inches). This compact yet powerful size allows for installation in various industrial environments where space may be limited.
