Legrand DX3 Series Residual Current Device 20A 3+N-Pole 30mA Type AC 100kA 400V AC 4 111 87

Legrand 4 111 87 is a DX3 Series Residual Current Device (RCD) rated at 20 amperes with 3+N poles designed for operation at 400 volts AC. It features a trip sensitivity of 30 milliamps and a Type AC tripping characteristic, which is ideal for detecting AC fault currents in circuits. The device has a high breaking capacity of 100 kiloamperes, providing robust fault protection for industrial, residential, and commercial electrical systems.

This RCD mounts easily on DIN rails and uses screw connections for reliable wiring, with the input from the top and output to the bottom. The instantaneous break time ensures rapid disconnection to minimize electrical hazards. It complies with multiple rigorous standards including IEC 61008-1, IEC 61009-1, VDE, IEC 60947-2, and IEC 60898-1, confirming its suitability and safety for demanding electrical applications.

Legrand DX3 Series RCDs are designed for use with traditional supply busbars HX³, providing flexibility in wiring systems. They reliably detect leakage currents, enhancing safety by protecting users from electric shocks and preventing equipment damage due to earth faults.

Typical applications include residential homes, commercial buildings, industrial plants, and any installation requiring sensitive earth leakage detection and electrical fault protection.
