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 A in an EF catalog number is the instantaneous-only trip designation - Electrical.com describes the EF3A series as motor circuit protectors, magnetic only. 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 ampere figure tracks the motor, not the trip point; the adjustable magnetic pickup is what opens the circuit.

The ITE EF frame is obsolete and fits older ITE panelboards including the FC-1.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

Thirty amperes on the EF frame, the top of the A range. The nameplate reads Type ETI, adjustable instantaneous trip, with settings from 75 to 210 amperes.

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.
