We present the orbital and physical parameters of the detached eclipsingbinary V1200~Centauri (ASAS~J135218-3837.3) from the analysis of spectroscopicobservations and light curves from the \textit{All Sky Automated Survey} (ASAS)and SuperWASP database. The radial velocities were computed from thehigh-resolution spectra obtained with the OUC 50-cm telescope and PUCHEROSspectrograph and with 1.2m Euler telescope and CORALIE spectrograph using thecross-correlation technique \textsc{todcor}. We found that the absoluteparameters of the system are $M_1= 1.394\pm 0.030$ M$_\odot$, $M_2= 0.866\pm0.015$ M$_\odot$, $R_1= 1.39\pm 0.15$ R$_\odot$, $R_2= 1.10\pm 0.25$ R$_\odot$.We investigated the evolutionary status and kinematics of the binary and ourresults indicate that V1200~Centauri is likely a member of the Hyades movinggroup, but the largely inflated secondary's radius may suggest that the systemmay be even younger, around 30 Myr. We also found that the eclipsing pair isorbited by another, stellar-mass object on a 351-day orbit, which is unusuallyshort for hierarchical triples. This makes V1200 Cen a potentially interestingtarget for testing the formation models of multiple stars.
