ConditionReconditioned, 1-year operational guarantee

Inspected and tested to ESP Product Standards, one-year operational guarantee.

The trip on an MA-series breaker is non-interchangeable; the 600 A rating is fixed.

Superseded by the PowerPacT MGA36600, which uses an electronic trip unit and mounts in the same I-Line panelboards. Where a like-for-like thermal-magnetic replacement is wanted, a reconditioned MA36600 is the direct fit.

More Details

The MA36600 is a 600-amp three-pole I-Line breaker that plugs onto Square D I-Line bus, the direct thermal-magnetic replacement where an existing coordination study assumes the original MA curve. Inspected and tested to ESP Product Standards, one-year operational guarantee.

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.
