Guidance and manufacturer’s declaration-electromagnetic immunity
The MCB 300K100M, MPT 300K100M is intended for use in the electromagnetic environment
specified below.
The customer or the user of the MCB 300K100M, MPT 300K100M should assure that it is used in
such an environment.

IEC 61000-4-2 ± 6 kV contact
± 8 kV air ± 6 kV contact
± 8 kV air Floors should be wood,
concrete or ceramic tile. If floors
are covered with synthetic

applicable Mains power quality should be
that of a typical commercial or
hospital environment.

user of the MCB 300K100M,
MPT 300K100M
requires continued operation
during power mains
interruptions, it is
recommended that the MCB
300K100M, MPT 300K100M
be powered from an
uninterruptible power supply or
a battery.

characteristic of a typical
location in a typical commercial
or hospital environment.
NOTE UT is the a.c. mains voltage prior to application of the test level.
