SIEMENS 6ES7331-7KF02-0AB0 Covered by 12 months warranty
In case of short-circuit, the parts of a plant affected by a fault are subjected to
thermal stresses which are proportional both to the square of the fault current
as well as to the time required by the protection device to break the current. The
energy let through by the protection device during the trip is termed “specific
let-through energy” (I2
t), measured in A2
s. The knowledge of the value of the
specific let-through energy in various fault conditions is fundamental for the
dimensioning and the protection of the various parts of the installation
