MICROMASTER 411 ECOFAST - MICROMASTER 411

ECOFAST

ECOFAST (Energy and Communication Field Installation System) is a system for decentralization without control cabinets.

The ECOFAST variants of the MICROMASTER 411/COMBIMASTER 411 series of frequency inverters contain plug-in connectors for power-supply, communication-interface and motor connections in order to enable fast and problem-free replacement in time-critical applications and are completely compatible with ECOFAST technical systems.

MICROMASTER 411 ECOFAST inverters are available for the following power ranges:

0.37 kW to 3.0 kW, 380 V to 480 V 3 AC.

The MICROMASTER 411 ECOFAST can be used for single applications or integrated into automation systems.

For more information on technical features of the ECOFAST system, see Siemens Catalog IK PI and on the Internet under http://www.siemens.com/ecofast
