SIRIUS controls –
for reliable switching and protection of IE3/IE4 motors
IE3/IE4 motors have been mandatory for mains-fed
operation in Europe since January 1, 2015. The initial stage
applies to the 7.5 to 375 kW output range, while in the
second stage starting in 2017, the scope will be extended to
include outputs down to 0.75 kW.
From an electrical viewpoint, IE3/IE4 motors behave
differently than less energy-efficient models – they are
characterized by higher startup currents and modified
dynamic behavior. This entails certain challenges for our
controls.
The latest generation of SIRIUS controls has been fully
optimized for IE3/IE4. They avoid false tripping due to
higher inrush currents of IE3/IE4 motors, offer optimized
setting ranges for rated currents, and ensure reliable
switching and protection in any situation – the best
requirements for use of modern IE3/IE4 motors.
