RT0, RH Coupling Relays (Interfaces) Description DC operation IEC 0 947 and EN 0 947 (VDE 00) The RT0 coupling relays for switching motors and RH for auxiliary circuits are laid out to the special requirements of the connection to solid-state control equipment. Coupling relays have a low power consumption, an extended working range of the solenoid coil (0.7 to.25 x s ) as well as an integrated surge suppression against switching voltages (exceptions: RT0.-HB4. and RH..-HB40). Onto RT0. and RH coupling relays of size S00, auxiliary switch blocks cannot be fitted. Onto size S0, two singlepole auxiliary switch blocks can be snapped on.
