Key ratings — what they mean for fit
The 5SV5646-6KL: Type A detection covers sinusoidal AC residual currents plus pulsating DC. The 300 mA trip threshold is typical for fire protection or general shock prevention in industrial sub-distribution.
Mounting and integration
Mounts on a standard DIN rail (REG) in any position. Depth is 70 mm, width 72 mm, height 90 mm — the 4-module footprint matches the SENTRON family. Supply can enter from top or bottom. IP20 rating applies once the distribution board is installed with conductors connected; the device itself is not sealed for wet environments. Ambient operating range is -25 °C to 45 °C, with storage from -40 °C to 75 °C.
