MICROMASTER 4 output choke 200-480V 3AC 80A (HO/CT) /104A (LO/VT) stand-alone FS E-0.111 MH Electrical choke SINAMICS output choke for the modular frequency converter SINAMICS G120, as well as the MICROMASTER 4. Output chokes are used to reduce the capacitive compensating currents and voltage gradient (du/dt) for motor cables > 50 m (shielded) or > 100 m (unshielded). The output choke covers the three-phase voltage range 3AC 200 V to 600 V. It is available as a substructure for sizes FSA to FSC. Electrical choke SINAMICS output choke for the modular frequency converter SINAMICS G120, as well as the MICROMASTER 4. Output chokes are used to reduce the capacitive equalizing currents and voltage gradient (du/dt) for motor cables > 50 m (shielded) or > 100 m (unshielded). The output choke covers the three-phase voltage range 3AC 200 V to 600 V. It is available as a base for sizes FSA to FSC.
