The Siemens 5SU9106-1KK16 is a SENTRON RCBO — a combined RCD and MCB in a single 18 mm-wide module. The 1P+N configuration protects one live conductor and switches the neutral; the neutral pole is not overcurrent-protected, so this is a single-pole protected device for single-phase final circuits.
Ambient temperature range is -25 to +45 °C, with derated currents above 30 °C — at 45 °C it carries 14.56 A, at 50 °C 13.92 A, at 55 °C 12.96 A.
The 5SU9106-1KK16 carries a 6 kA rated breaking capacity per both EN 60898 and IEC 60947-2, overvoltage category III, and IP20 with connected conductors in an installed distribution board. It is halogen-free and silicon-free. The product designation per DIN EN 61346-2 and DIN EN 81346-2 is F (protective device). Touch protection is provided on the terminals.
