[en] The Central Solenoid (C S) of ITER (International Thermonuclear Experimental Reactor) is designed to operate at 13 T, 0.5 - 1 T s, 5.8 K. There is an experimental evidence that reduced performances in variable field, not explained by A C losses, could occur in CIC (cable-in-conduit) conductors. Such ramp rate limitations have to be well understood in order to be avoided in the ITER conductors. In the ENEA (National Agency for New Technology, Energy and Environment) Frascati Laboratory a facility has been assembled to test in pulsed regimes (up to 8 T, 4 T / s, 12 K) the ENEA (National Agency for New Technology, Energy and Environment) Nb₃ Sn CICC coil. The characteristics of the coil (dimensions, CIC conductor, strand designed for use in variable field). Main objectives of the program are experimental data on ramp rate limitations, pulsed-current distribution in the cable, limiting currents and global A C losses. This paper reports the results of the measurements carried out up now, and those of the simulations performed by means of the thermo-hydraulic analysis code SARUMAN
