RCBO for branch-circuit protection with residual-current monitoring
The C-curve means magnetic trip occurs at 5–10× In (30–60 A for this 6 A unit), suited for circuits with moderate inrush — think lighting banks, socket outlets, or small motor starters where the starting surge won't exceed that window. The higher IEC figure gives fault-clearing headroom for industrial panel applications where prospective short-circuit current may exceed the domestic standard's limit.
Thermal derating and mounting flexibility
Rated current is 6 A at 30 °C ambient, derating linearly to 4.7 A at 70 °C. In a crowded enclosure with elevated internal temperature, size the load to the derated value — the 70 °C figure is the operating limit, not storage. The 72 mm depth fits standard 70 mm installation depth distribution boards; the 36 mm width occupies two modular units on the DIN rail.
Surge withstand and pollution environment
Rated surge voltage resistance is 4 000 V, with surge current withstand of 3 kA at 8/20 µs waveform — relevant for installations in overvoltage category III environments (fixed installations with transient overvoltages).
