    Good breaker. No problems. Direct replacement.

    Superbreakers was great to work with. The salesman checked and didn't have the breaker I was looking for, but found one at another location, had it shipped to me next day air, and it worked out great. Glad to see this type of customer service. I will call on them again when needed.
