Why the H costs more. The H suffix denotes high interrupting capacity: 22,000 amperes rather than the 10,000 of a standard BQ1B020. It is specified where the available fault current at the panelboard exceeds what a standard device can safely interrupt, and a standard BQ is not a substitute. The difference is entirely internal — the two look identical on the panel front.

More Details

Available fault current is what decides between this breaker and an ordinary BQ1B020. Where a panelboard sits close to a large service transformer, the calculated fault current at the bus can pass ten thousand amperes, and every branch device in that panel has to be rated to interrupt it. The H answers that at twenty-two thousand amperes in the same physical envelope, so no panel modification is involved and nothing on the panel front distinguishes the two. That last point matters: a panel repopulated from a photograph can quietly lose the rating it was specified for. Each unit is tested for trip function and inspected to ESP Product Standards before returning to stock.

What is "surplus new"?

Surplus new means the item has never been installed or put into service. It may not arrive in its original packaging, but it has never been used.

What does "reconditioned" mean?

Reconditioned items have been inspected, cleaned, and tested to confirm they operate to the manufacturer's original specifications. Every reconditioned item we sell carries a one-year operational guarantee.

How fast will my order ship?

In-stock orders placed before 12pm PST usually ship the same business day via UPS, with tracking provided.
