Each unit is inspected and tested to ESP Product Standards and backed by a one-year operational guarantee.

The Siemens BQD line remains in current production, so this reconditioned unit is a direct drop-in for existing 480Y/277V panelboards at well under new-unit cost, backed by a one-year operational guarantee.

More Details

The BQD345 is a 3-pole, 45-ampere BQD (Sentron) molded case circuit breaker rated for 480Y/277V AC service. It bolts directly to the panelboard bus, which keeps the connection tight under vibration and thermal cycling in a way plug-in devices cannot match. Thermal-magnetic tripping handles sustained overloads through the bimetal element and clears short circuits through the magnetic element, with no field adjustment to drift out of calibration. ESP can confirm compatibility against the panelboard schedule before shipment if the existing catalog number is uncertain. ESP's inventory is drawn from decommissioned switchgear, contractor overstock and manufacturer surplus, so availability on any single catalog number moves. Quantities listed on this page reflect what is physically on the shelf in Spokane rather than a distributor drop-ship position.

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.
