It integrates earth-leakage detection and thermal-magnetic overcurrent trip into one DIN-rail unit, saving a pole position in the panel compared to separate MCB + RCCD. Earth-leakage sensitivity is 100 mA, integrated into the same body — no add-on module or external toroid. That sensitivity level is typical for circuits where 30 mA nuisance tripping is a concern (e.g., fixed equipment with natural leakage) but still provides personnel protection in some jurisdictions; verify local code for socket-outlet circuits.
Clip-on mounting to DIN rail, 18 mm width (2 x 9 mm pitches), 110 mm height, 77.5 mm depth. Padlockable with a Ø 4 mm padlock for lockout/tagout. Screw-clamp terminals: top accepts 1–25 mm² rigid or 1–16 mm² flexible; bottom accepts 1–16 mm² rigid or 1–10 mm² flexible. Tightening torque 3.5 N.m top, 2 N.m bottom. Strip length 14 mm top, 13 mm bottom. Rated for TN earthing systems, 50 Hz network frequency. The toggle control gives ON/OFF indication and a contact position indicator confirms the state of the main contacts — useful during commissioning and fault-finding.
Compliance: certified to IEC 61009-1 and IEC 61009-2-2, the harmonized standards for RCBOs. Tropicalisation class 2 indicates the device is treated for resistance to heat and humidity — 95 % RH at 55 °C. Suitability for isolation marked — it can be used as a disconnecting means. Electrical durability: 5000 cycles. Mechanical durability: 20000 cycles. Limitation class 3 — energy-limiting performance that reduces let-through energy under short-circuit conditions, protecting downstream equipment.
