Doepke DFS 4 063-4 003-F Audio: High-End Residual Current Circuit Breaker for Hi-Fi and A/V Systems
The Doepke DFS 4 063-4 003-F Audio is a premium residual current device (RCD) engineered specifically for high-performance audio and video systems. It combines advanced electrical protection with an internal architecture optimized to deliver a clean, interference-free power supply—crucial for demanding Hi-Fi and A/V setups.
At first glance, it may resemble a conventional RCD, but internally it's been completely reengineered for audiophile applications. Instead of traditional inductors, it features a straight, non-coiled rod design that drastically reduces inductance. This allows current to flow more freely, eliminating potential bottlenecks that could impact your system’s dynamics and transient response.
Its oversized contacts, made from carefully selected materials, ensure extremely low contact resistance, exceptional connection pressure, and ultra-low noise—forming a clean electrical foundation for any high-end audio or video system.
Additionally, it offers full protection against both direct and indirect contact, even in the presence of non-sinusoidal waveforms produced by modern switching power supplies (SMPS), now common in home environments. With a differential sensitivity of 30 mA, it ensures not only personal safety but also optimal system performance.
