What drives the number
  • The highest-value breakers we buy.
  • Drawout units with cradle, Micrologic trip unit, and racking handle carry the most. A missing trip unit or cradle cuts the number hard.
  • We do not publish prices. Metal, demand, and condition move them. You get a written number for your units.
From the yard

Do not separate a drawout breaker from its cradle unless you have to. A matched breaker and cradle is a resale set. A breaker alone means the buyer has to find a cradle that fits, and the price reflects that.

The business end

Line and load terminals, I-Line jaws or bolt-on tabs, and the trip unit or rating plug if it has one.
