Mains filter (EMC)
The EMC product standard (EN 61800-3 Amendment
A11 (2000)) covers the specific EMC requirements stated
for drives (tested with otor and cable) within the EU.3.
EMC standards such 55011, 61000-6-3/4,
apply industrial and household equipments and
systems including drive com ponent inside. cable.
All braking resistors are equipped with thermal sensor
as standard.
ABB 3AFE68675073 REV 19. Mains chokes are typically used to:
■ reduce harmonics the mains current
■ achieve reduction the r.m. This level corresponds the
A limits for Group equipm ent according 55011.
EN 55011 and 61000-6-3/4 not specify cable
length nor require otor connected load.
Braking resistors
Depending the application, external braking
resistor may needed convert the kinetic energy
generated into thermal energy. selection resistors is
available for different kinds pulse duty performance.2009.
The emission limits are com parable according the
