The relay of control of phases for protection of three-phase electric motors at an error of alternation of phases (violation of sequence), loss of one of phases, fastening on a DIN-lath or screw on the assembly panel. FK-04, TENSE

Algorithm of operation of this relay of control of phases following:

Connect the FK-04 relay to food as it is specified on the scheme of connection given below.

If the linear tension of all three phases is in limits of 154 - 275 volts and the sequence of phases is not broken, then the relay of phases is in working order - contacts 2-3 are closed, the RLY indicator is illuminated, the indicator does not shine. At a power surge for the specified range or violation of alternation of phases of the relay highlights the indicator, disconnects contacts 2-3, closes 1-2 and switches off the RLY indicator.

At restoration of sequence of phases of the relay passes into position.
