AC Breaker for DC application?

[coil]

Hi all,

I would just like to know if a 110V AC circuit breaker can be applied to 48V DC applications, for the same tripping current?

The said breaker would be used for a dummy load for battery testing.

Thanks.

Hmm this an MCB with magnetic for short circuit and thermal for overload? Bearing mind mind that you lose magnetic using DC and hence short detection I wouldnt have thought so, you wouldnt want the batteries to explode or be damaged as it didnt cut out fast enough. As P=IV lower V means more I for same power required to heat the bi-metalic strip to disconnect
