It protects a single pole (1P + Ns) outgoing circuit against overload, short-circuit, and earth leakage, all in one DIN-rail footprint. Earth-leakage protection is integrated at 100 mA sensitivity — a common specification for circuits feeding socket outlets or general-purpose equipment where 30 mA personal protection isn't mandated, but some ground-fault coverage is still wanted.
Plug-on mounting onto Isobar A or Isobar B distribution boards. The 18 mm width (2 × 9 mm pitches) matches the standard modular grid — one RCBO per outgoing way. Neutral is on the left, and the upstream connection uses a plug-on neutral tail, so no separate neutral bar link is needed on compatible boards. Torque to 3.5 N·m top, 2 N·m bottom. Strip length 14 mm top, 13 mm bottom. IP20 finger-safe, IP40 inside the modular enclosure.
Designed and certified to BS EN 61009-1, IEC 61009-1, and IEC 61009-2-2 — the harmonised standards for RCBOs. Tropicalisation class 2, overvoltage category II, rated for TN earthing systems.
