ADR432C-30 is a 32A high immunity Type A 4 pole RCBO designed for three-phase circuits where reliable overload, short-circuit, and residual current protection are required. With 30mA residual current protection, 6mA DC detection, and a 10kA breaking capacity, it is well suited to EV charger installations, heat pump systems, and other inverter-driven applications.
Installer Tip: The twin-handle trip indicator helps show whether the fault was caused by overcurrent or residual current, making diagnosis and reset quicker on site.
