        NLS 30839 | Single Pole 6kA RCBO | 20Amp A-Type

        The NLS 30839 20A Single Pole RCBO 6kA A Type offers robust protection by combining overload, short-circuit, and earth-leakage detection in one compact module. Engineered with A Type sensitivity, it safeguards against both AC and pulsating DC residual currents - making it ideal for circuits with modern electronic loads.

        This unit comes pre-wired with line and load tails for a quick, tidy install and features a reduced-depth profile for easier placement in confined switchboard spaces. Approved to AS/NZS 61009.1, it ensures safety and compliance across a range of residential applications.

        NLS 30839 Features

        • 20A Current Rating suitable for higher-demand single-phase circuits.
        • Single Pole (1P) RCBO combines circuit breaker and RCD in one device.
        • 6kA Breaking Capacity handles residential fault currents reliably.
        • Type A Protection detects both AC and pulsating DC residual currents.
        • DC Tolerance ideal for circuits with potential DC leakage from appliances.
        • Pre-Attached Wiring simplifies installation and reduces time on site.
