Breaking capacity and derating
The higher IEC figure applies when the RCBO is used as a distribution-board component under the industrial standard — useful for higher-fault installations. The 13 A rating at 30 °C derates to 12.48 A at 40 °C and further to 10.01 A at 70 °C. For a panel that runs warm (55 °C ambient), expect 11.57 A continuous — plan the load accordingly.
Depth is 77 mm, installation depth 70 mm. Supply can be connected from either top or bottom, which simplifies panel wiring. IP20 protection applies only when the distribution board is installed and conductors are connected — treat it as a panel-internal device, not for wet or outdoor enclosures without additional sealing.
