It combines a C-curve MCB characteristic with a Type A residual current device set to 100 mA, per the datasheet.
The C characteristic means the magnetic trip operates at 5 to 10 times rated current (160–320 A for this 32 A unit), suited for circuits with moderate inrush — typical for motor starters, small transformers, or lighting banks in commercial panels. The Type A residual detection handles pulsating DC fault currents up to 6 mA smooth DC superimposed, covering single-phase rectified loads like switched-mode power supplies and LED drivers. The 100 mA sensitivity is a deliberate choice: it's above the 30 mA required for socket-outlet personal protection, so this unit is intended for equipment or submain protection where a higher trip threshold avoids nuisance tripping from leakage in longer cable runs or filtered supplies.
Panel integration
At 7 module widths (roughly 126 mm on a standard 18 mm/module DIN rail), this 4-pole RCBO fits a compact sub-distribution board. The neutral pole is switched and protected internally — no separate neutral bar needed downstream.
