Der RCD Typ AC ist ähnlich wie der RCD Typ A, bietet jedoch zusätzlich Schutz vor pulsierenden Gleichfehlströmen. Er wird normalerweise in Umgebungen eingesetzt, in denen elektronische Geräte mit Halbleiterkomponenten verwendet werden, da diese Art von Geräten natürliche Gleichfehlströme erzeugen können.

· RCD (Residual Current Device) is an automatic circuit breaker when it detects an imbalance in the amperage. RCDs are designed to protect people from electric shock when they come into contact with live equipment. RCDs provide a level of personal protection that conventional fuses and circuit breakers cannot. What is RCD.

An RCD, or residual current device, is a life-saving device which is designed to prevent you from getting a fatal electric shock if you touch something live, such as a bare wire. It can also provide some protection against electrical fires. RCDs offer a level of personal protection that ordinary fuses and circuit-breakers cannot provide.

Speed: UK regulation BS EN 61008 stipulates that RCDs must trip within certain time frames depending on the amount of current imbalance. 1 x In = 300ms. 2 x In = 150ms. 5 x In = 40ms. 'In' is the symbol given to tripping current-so, for example, 2 x In of 30mA = 60mA.RCDs used in commercial and industrial environments have higher mA ratings
