ConditionReconditioned — 1-year operational guarantee

This unit is sold reconditioned, inspected and tested to ESP Product Standards, and guaranteed to operate normally for one year from the date of sale.

This device provides no overload protection. The nameplate reads Type ETI, circuit breaker with adjustable instantaneous trip. It supplies short-circuit protection in a combination motor controller and relies on a starter and overload relay for everything slower. It is not a branch-circuit breaker.

The ITE EF frame is obsolete and fits older ITE panelboards including the FC-1. Siemens absorbed the ITE line and has no drop-in successor. ESP stocks tested reconditioned EF units across the range.

More Details

Fifty amperes continuous, three poles, 600 volts, on the ITE EF frame. The nameplate reads Type ETI, circuit breaker with adjustable instantaneous trip: magnetic only, with five settings from 160 to 470 amperes and no overload element. It belongs in a combination motor controller with a starter and overload relay. Fits older ITE FC-1 panelboards.

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.
