DC Over Load Protection

02/25/2013 8:20 AM

How we supply Overload relay for DC power circuit. Normal CT is not applicable for DC. Shunt is one option. Is there any other option?

Several come to mind:

  • Electromagnetic circuit breakers
  • Thermal circuit breakers
  • Fuses
  • Etc.

(1) There are DC CTs which are specialised. You can search the web, especially for patents.

(2) Magnetic releases are more common for DC protection.
