It occupies 4 module-widths on a DIN rail — that's 72 mm of panel space for a combined overcurrent and earth-leakage device.
The 32 A rating on the C curve is sized for final sub-circuits feeding socket outlets, lighting banks, or small fixed equipment up to about 7 kW on a 230/400 V supply. Type A residual current detection (100 mA) covers pulsating DC fault currents from electronics, variable-speed drives, or switched-mode power supplies — the kind of leakage a plain AC-sensitive RCD might miss. The 2-pole form factor switches both line and neutral, which is standard for single-phase final circuits in TN or TT earthing systems.
Panel integration
Snap-on mounting to standard 35 mm DIN rail, 4 module-widths (72 mm). The busbar comb bridges across the line terminals for multi-pole distribution boards. Spring-cage terminals accept 1.5 to 25 mm² conductors — sized for the 32 A rating with standard PVC cable.
