IEC 60947, EN 60947.
The 3RT20 coupling contactors for
switching motors are tailored to the
special requirements of working with
electronic controls.
AC and DC operation
The 3RT20 1 coupling contactors
cannot be expanded with auxiliary
switch blocks.
Coupling contactors have a low
power consumption and an extended
solenoid coil operating range.
Depending on the version, the
solenoid coils are supplied either
without overvoltage damping or with
a diode, suppressor diode or varistor
connected as standard.
