DC protection
(OP)
I am currently working on solid state transformer protection system design. I have to design dc protection of 400 Volt dc link but constraint is that I can not use circuit breaker for protection as DC circuit breaker is expensive. Any ideas and suggestions are welcome

Remember also that that the breaking capacity is also reduced for use DC systems. BS88 and IEC60269 fuses can be used on DC, but I'm not sure what voltage they go up to.

Mersen (Ferraz) can manage 1600A at 750V DC if you can accept the ultra-fast characteristic.
