Hello,
I've been in touch with a Doepke employee and he send me an email with this:
"The DFS4 Audio is no a fuse or MCB, it is an RCCB, which protects user of residual currents – means human protection against electric shock.
On the other hand it protects against fires.
- The DFS Audio has been developed exactly for audiophile purposes, the goal was to get as much as low impedance as possible, due to the construction of this internal parts.
All other DFS (which is the series in general) have not this internal setting. So DFS4 EV for example is for special vehicle charging purposes.
So there are 3-4000 different DFS4 (4 pole) or DFS2 ( 2pole) in Doepkes range, all for different applications.
- No Doepke DFS4 or DFS2 breaker has been certified for the US – so not UL listed. We do sell some special DFS4 RCCCB´s in the US but for very special applications, where a UL certification is not mandatory.
Doepke was in the 1950´s among the first developing and producing companies of RCCB´s. It was 3 companies and from those 3 only Doepke is still existing , as “ the specialist” for residual current protection, with the widest range of RCCB´s at all on the market.
We are producing special RCCB´s for almost all major players in the low voltage switchgear market, for example, ABB, Siemens, Legrand, Schneider-Electric, Hager etc.
So we know what we are doing since over 60 years."
