RCCB – SENSITIvE TO ALTERNATING CURRENT TyPE AC<br />
RW product range, undelayed tripping acc. to IEC 61008<br />
Function<br />
RCCB independent of the mains voltage for realising the<br />
protective measure “protection through automatic power<br />
supply cut-off”, in compliance with the requirements of<br />
international construction regulations.<br />
Characteristics<br />
· 2-pole or 4-pole<br />
· Large range of products with<br />
- Rated currents from 16 A to 125 A<br />
- Rated residual currents 0.03 A to 0.5 A<br />
· Tripping independent of supply and auxiliary voltage<br />
· Sensitive to AC residual currents (type AC)<br />
· High short-circuit strength<br />
· Double-sided two-tier terminals for large conductor<br />
cross-section and busbar<br />
· Switch-position display<br />
· Window for labels<br />
· Multi-functional switching knob with three functions:<br />
- On (top position)<br />
- Off (bottom position)<br />
- Display “tripped” (centre position)<br />
If the RCCB trips due to a fault, the switching knob<br />
stays in the centre position<br />
type of mounting<br />
· Quick mounting on DIN-rail in accordance with<br />
EN 60715 in any standard distribution<br />
· Any mounting position<br />

Areas of application<br />
Power supplies of residential and single-purpose buildings<br />
as well as industrial facilities<br />
with TN-S and TN-C-S networks. In IT networks, RCCBs of<br />
the RW series for switch-off in case<br />
of a second failure can be provided for.<br />
Excluded is the use in TN-C networks and for protecting systems<br />
in which electronic equipment might cause DC residual<br />
currents or residual currents with frequencies of ≠ 50 Hz.
