How can we help you today?
Is there a breaker rated for DC application that has an adjustable time delay setting?
Issue:
Does Square D offer a DC breaker that has a time-delay adjustment setting?

Product line:
Molded case circuit breakers

Resolution:
No. In order to have an adjustable time delay setting, the breaker must have an electronic trip unit, and no electronic trip breakers are rated for DC application.
