The S800 high performance MCB limits energy and current in case of a short-circuit power cutoff. It’s specially developed double arcing chamber system ensures these excellent operating properties. In this way, each single pole of an S800 can build up d ouble the amount of reverse voltage in comparison to conventional single arcing chamber systems. The electric arc is therefore eliminated quickly and safely in the arcing chamber. This provides additional protection in case of incorrect wiring.
