It fits standard distribution boards where both earth leakage and short-circuit protection are needed on a single outgoing circuit, saving a pole position compared to separate MCB + RCCB. The 30 mA residual sensitivity catches direct-contact earth faults per IEC 60364 — the standard threshold for socket-outlet and general-purpose circuits where additional protection against lethal shock is required. Four poles cover three-phase + neutral circuits, so this RCBO protects all live conductors including the neutral against both overload and earth leakage.","metaTitle":"2CSR256040R1164 DS203NC C16 AC30 ABB 2CSR256040R1164","metaDescription":"ABB DS203NC RCBO, 16A rated current, 30mA trip sensitivity, 4 poles, Type C characteristic.
