The 5SU1354-0KK32: The 32 A rating at 30 °C is the nominal current; at higher ambient temperatures the continuous current must be derated — at 40 °C it is 30.4 A, at 50 °C it is 28.8 A, and at 70 °C it is 24.64 A. The 30 mA residual current (tripping fault current rated value) provides protection against direct contact for AC-type earth faults (sinusoidal AC residual currents only).
Installation and deployment context
The supply can enter from either the top or bottom. Halogen-free and silicon-free construction. The RCBO occupies 2 MW (modular width) units, so it replaces a standard 2-pole MCB slot in a consumer unit or sub-distribution board.
