Discriminator

DT3000 ParameterDiscriminator =Doff= Inactive

Also known as a making current release, the discriminator in the DT-3000 is active for 10 cycles

after the breaker closes. The EDR-3000 has a similar function called Switch on to Fault (SOTF)

with a selectable time.

Maximum setting to prevent

tripping after delay

Adaptive setting only active
