It combines a B-curve overcurrent trip at 16 A with an integrated residual current device in a single 1P+N pole configuration — one protected pole plus a switched neutral.
B-curve and thermal derating
At a 30 °C ambient the unit carries 16 A continuously; at 40 °C it derates to 15.2 A, at 50 °C to 14.4 A, and at 70 °C to 12.32 A. This thermal derating curve means the installer must account for enclosure heat rise when loading the circuit near the nominal rating, particularly in densely populated distribution boards.
The housing measures 77 mm deep by 36 mm wide by 90 mm tall, occupying 2 modular-width units (MW) on a standard DIN rail. Installation depth is 70 mm. IP20 protection applies once the distribution board is installed with conductors connected — this is an enclosed-panel device, not rated for exposed or washdown environments.
