MX403B
DANGER
For all other applications at the low-voltage installation
there is a risk related to:
S Electric shock
S Arc flash burns
S Arc blast explosion and
S Other phenomena
The MX403B is only suitable for rated voltages within the
measurement categories described - the MX403B is not
suitable for any other applications at the low-voltage in­
stallation and its use here is not permitted.
Outside the measurement categories
The following applies to test and measuring circuits
without a rated measurement category (formerly CAT I):
Whether the MX403B is suitable for test or measuring
circuit applications not intended for direct connection to
the supply network can only be determined by an accur­
ate analysis of the operating voltage, peak voltage, loop
impedance, occasional overvoltage and transient over­
voltage of these circuits. The following characteristics
apply to the MX403B in this respect:
S Peak voltage: max. 1250 V
S Loop impedance: min. 100 m
(see EN 61010-2-030:2011 Table AA.1)
S Occasional overvoltage: none
S Transient overvoltage: "3000 V
