Breakers and trip units
What we stock
A breaker has to match its panel on frame, voltage, amp rating, and interrupting rating. Close is not good enough, so we ask for the label every time. Most requests are for a replacement or a spare for a panelboard or a power distribution unit, along with trip units and the small accessories that go with them.
We tell you what we found and what we could not confirm. The final check that a breaker is right for an installation belongs to the installer, and we say so on the quote.
