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).

Y-series in the 300VDC (and above) version has a permanent magnet to help extinguish the arc which is created inside the circuit breaker when switching a DC voltage.  In cases where the application calls for a product which is not polarity sensitive there is a range (YB) without the magnets. Then it operates with 150 VDC in one module and 300VDC with 2 modules in series. 

 

Just as the rest of the rail mounted MCBs, Y series can be delivered in both grey version with 45 mm front escutcheon and black version with 57 mm front escutcheon. 

 

Y-series can be delivered with factory fitted auxilliary contact.

 

Y series has different approval profiles depending on what the application area is: 

  • YA = Tele/Datacom 
  • YB = Alternative energy/Energy storage (unpolarized product) 
  • YR = Rolling stock and railway signaling 
  • YS = Switch version without overload protection.
