Block fazokontrolny FC-75 for the control of phases in a three-phase motor drive control pointer circuits. Unit monitors the presence of the phase currents in the conditions according to GOST 15150 U3.1, but for operation at temperatures from minus 10 ° C to plus 40 ° C and relative humidity of 98% at a temperature of 25 ° C.
Block FC-75 has a plug-in coupling is mounted on the relay cabinets and cupboards.
DC voltage lockout (Ub) at the time of passage of the primary windings of transformers unit three-phase 50 Hz and residual DC voltage (Uost.) arising at open circuit one of the AC phase, measured at the output terminals at a load of (1200 ± 60) ohms are given in table.
