Small contactors. These will switch up to about 150V DC with the magnetic
blowouts fitted. But they are a 80A device.

 

The alternative is to use a four pole relay and wire four breaks in series
then test it and see what life it gives. We did this with the Albright SW121
when used as an AC- DC changeover contactor.

Subject: [EE]Need relay to switch 135VDC @ 1Amp

 

Hello,

 

As the title title states, I need to switch 135VDC

at 1 Amp using a relay - and I am required to 

use a mechanical device (no solid state relays 

allowed).  Most relays I can find easily switch 

220AC, but only very low DC voltages.  

 

If possible, it would be nice if it was a DPDT 

that could also handle 50VACrms.

 

Any suggestions?  

 

Thanks.  

 

Ken
