Power distribution and cable protection
MOVIFIT
®
FDC is equipped with integrated line protection for the supply cable to the
MOVIGEAR
®
and DRC drive units. This line protection is provided by a type ABB
MS325 motor protection switch integrated in the ABOX.
The type ABB MS325 motor protection switch protects the supply cable of the
MOVIGEAR
®
and DRC drive units and is designed for a cable cross section of
4 x 2.5 mm
2
(with factory setting: 15 A) or 4 x 4.0 mm
2
(with factory setting 20 A).
Therefore, make sure during project planning that no more than 15 A or 20 A of total
current runs through the connected MOVIGEAR
®
and DRC drive units. For UL-compli-
ant installation, additional restrictions must be observed (see chapter "UL-compliant in-
stallation" (page 44).
For power bus configuration, check to make sure that short-circuit and overload protec-
tion (in accordance with DIN VDE 0100-430) are still ensured for the supply system
cables to the MOVIGEAR
®
and DRC drive units depending on line impedance, cable
lengths and contact resistances.
Note the technical data and the characteristic curves of the motor protection switch. The
data of ABB MS325 is available from ABB.
