It combines overcurrent and residual current protection in one 3-module-width (54 mm) package, saving a DIN-rail position compared to a separate MCB+RCCD pair. The Type A residual-current element detects pulsating DC as well as sinusoidal AC earth faults — the standard choice for circuits with single-phase electronics or rectified loads.
Temperature derating and panel fit
At 30 °C ambient the device carries the full 32 A. Derate to 30.4 A at 40 °C, 29.76 A at 45 °C, 28.8 A at 50 °C, 27.84 A at 55 °C, 27.2 A at 60 °C, and 24.64 A at 70 °C. In a sealed enclosure or high-ambient panel, use the 40 °C column for sizing. Mounts in any position, 70 mm installation depth, 77 mm body depth. Three modular width units (54 mm) snap onto standard DIN rail. IP20 with distribution board installed and conductors connected — not for wet-area standalone use.
