voltage drop of ESX10-T and tolerance of
trip point (typically 1.1 x I n = 1.05 ... 1.35 x I n ) have been taken into account.

• The trip time is typically 3 s in the range between 1.1
• Electronic current limitation occurs at typically 1.8 x I n
• Without this current limitation a considerably higher

which means that under all overload conditions
(independent of the power supply and the resistance of
the load circuit) the max. overload before disconnection
will not exceed 1.8 x I n
time is between 100 ms and 3 sec (depending on
overload or at short circuit).
overload current would flow in the event of an overload
or short circuit.
