The 16 A rated current at 30 °C and C tripping characteristic mean it handles moderate inrush loads — typical for mixed lighting and small motor circuits in commercial panels — while the 30 mA residual threshold protects against direct-contact shock hazards. For circuits with variable-speed drives, UPS systems, or LED drivers that can generate non-sinusoidal leakage, a type A or type B RCD would be required.
The 16 A rating holds at 30 °C ambient; at 40 °C it derates to 15.2 A, at 45 °C to 14.72 A, at 50 °C to 14.24 A, and at 55 °C to 13.76 A. If the panel internal temperature runs above 30 °C — common in crowded enclosures — size the upstream protection and load accordingly.
Regulatory and compliance notes
Rated insulation voltage is 264 V, surge voltage resistance is 4 kV, and the energy limitation class is 3. The product designation per EN 61346-2 and IEC 81346-2 is letter F (protective device).
