Definition TTA: Switchgear assembly corresponding, to a large degree, with the original type or system of switchgear assembly type-tested
in accordance with these standards.
**
Design verification by testing: When an assembly has previously been tested in accordance with IEC 60439-1 , and the results fulfil the
requirements of IEC61439 -1 / -2, the verification of these requirements need not to be repeated
