RCCB RCD Circuit Breaker 2 Pole 30mA 16A 25A 40A 63A AC Type with Dual Protection and Sensitivity Trip

Earth Leakage Circuit Breaker D463 Key specifications Type: Earth leakage Model number: D463 Poles and sensitivity: 2pole, 30 mA residual current sensitivity Rated voltage: 230V AC Rated frequency: 50/60 Hz Rated current: 16A; available size option 32A Residual current characteristic: AC Trip types: Magnetic for 30 mA to 300 mA ranges, electronic for 10 mA range Electromechanical endurance: more than 20,000 cycles Contact design: silver alloy contacts with arc resistance and service life exceeding 10,000 operations Installation: Standard 35 mm DIN rail, 1P plus N width 36 mm What this product does and why it matters Dual protection in one device: combines leakage detection with overload and short circuit protection to reduce the number of separate protective devices required. This simplifies wiring and reduces component count in a distribution board. sensitivity leakage detection: 30 mA residual current trip provides protection against hazardous earth leakage currents while remaining suitable for general electrical circuits. Robust, longlife construction: flameretardant housing and silver alloy contacts resist arcing and mechanical wear, delivering reliable operation over many cycles in residential and commercial installations. Wide voltage tolerance: designed to remain functional across a broad supply range, suitable for installations where voltage can fluctuate significantly. Space efficient: narrow 36 mm width for the 1P plus N module saves panel space and allows higher circuit density on a standard 35 mm DIN rail. Performance and compatibility Compatible with 230V AC systems operating at 50 or 60 Hz. Residual current characteristic AC is suitable for common singlephase circuits. Available trip technologies support applicationspecific sensitivity needs: magnetic trip for medium and residual current settings, electronic trip for sensitivity 10 mA applications. Practical applications Domestic distribution boards for circuits feeding bathrooms, kitchens, and outdoor outlets where leakage protection is required. Small commercial and light industrial panels where combined overload and earth leakage protection reduces wiring complexity and conserves panel space. Temporary power supplies and sites with unstable supply voltage where wide voltage adaptation helps maintain reliable protection. Benefits at a glance Consolidates leakage and overcurrent protection into one compact module Durable components and cycle life reduce maintenance and replacement frequency Narrow module width maximizes available space in distribution cabinets Multiple trip options and rated current sizes provide flexibility for various installations Installation notes Fits standard 35 mm DIN rail mounting Select the appropriate trip sensitivity and rated current for the specific circuit and local regulations before installation Model D463 provides a compact, durable solution for combining earth leakage detection and overcurrent protection in singlephase distribution systems.
