1.2 Withdrawable Module Design
MStart and
MFeed modules of withdrawable
design provide a maximum of plant and
operator safety.
As per definition in IEC 61439-1/-2
withdrawable modules can be electrically
disconnected (“withdrawn”) without the help of
a specific tool with respect to the main
incoming circuit, the main outgoing circuit as
well as the auxiliary circuits.
MStart and MFeed are standardized
components, ready-to-use and offered for a
wide application range leading to maximum
flexibility.
The high device packing density allows a
comparatively low footprint of the MCC.

1.2.1 Main Characteristics
 Multi-functional operating handle
connecting to module interlocking
mechanism (see page 52)
 Ergonomic module handle to withdraw the
module
 Status display (4 LED) integrated in
module front
 Module rear wall with integrated contact
system and sensors
 Control terminal block
MStart and MFeed comprise the power circuit and
measurement functionality, thus they are
decoupled from integrated control.
Integrated control and protection functionality is
performed by the allocated MControl located in
the control cable compartment.
Utilisation of conventional feeder modules for
energy distribution is possible for conventional
control instead of MControl functionality.
