Notes: The values stated in the table apply for 3 and 4 pole fixed
mounted devices with an equal load distribution.
On 4 pole devices the current in the neutral conductor is equal to zero.
The total resistive load is the measured value for a 3 pole or a 4 pole
switch (independent of In and the type of release).
The total resistive load for a switch or withdrawable plug results from:
the resistive value for fixed mounting + resistive value
for plug-in or withdrawable.
The heat dissipation can be calculated with the
formula: P = 3 x R x I²
