Y13mm DC MCB up to 600VDC 0,5-50A
High DC voltages, like 300-600VDC, is more and more common in power distributions as a way to reduce the amount of copper in cables and busbar systems. Up to now there has been a challenge to find a MCB that in a safe way can handle such high DC voltages. Now the solution to this is the new development from CBI, the Y-series. It is a revolutionary product that is build on the same proven Hydraulic-Magnetic principle like the rest of the CBI products. Meaning that no de-rating is needed due to the ambient temperature. Y-series can handle 300VDC in one 13 mm module and for applications that require 400 or 600 VDC they can be delivered serial connected from factory and is the 2x13 mm wide. If you need to break both plus and minus in your application, the Y-frame can be delivered as a real electrical 2 pole circuit breaker. In that case up to 300 VDC is 2x13mm wide and 301-600 VDC is 2x13 +2x13mm. I.e. total width 52 mm (4x13).
