ZS1c
The test terminal board ZS1c (for four-wire) is for electrical equipment which require replacement or inspection of measuring instruments during the operation (when disconnecting or connecting electricity in the secondary circuits of measuring current transformers) and where it is necessary to fulfill the requirement of continuity of the secondary circuit of the measuring current transformers.
Test terminal board ZS1c is arranged so that the current terminals P are continuous. Conductive connection of adjacent current terminals of the same polarity is done springboard M and tightening the screws S. Neutral terminal N is divided into two halves. Conductive connection of the two halves of the clamp is made clutch K.
