This is a motor circuit protector, not a circuit breaker. It has a magnetic trip only and no thermal element, so it provides no overload protection. It is listed for use in a combination motor controller with a separate overload relay, and must not be applied as a branch-circuit breaker.

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

The GJL (J-frame) Mag-Gard line is out of production. ESP stocks tested reconditioned units for Square D motor control centers and combination starters still in service.

More Details

A 3-pole GJL device rated 3A at 600Y/347V AC, the GJL36003M01 is specified for Square D motor control centers and combination starters. ESP inspects and tests each unit to ESP Product Standards before it is listed. Buying reconditioned keeps an existing board in service without the cost, lead time and outage window that replacing the interior would demand. A motor circuit protector is not a circuit breaker with a different label. It has no thermal element at all, which means it will not respond to a sustained overload — only to a short circuit. UL lists it exclusively as part of a combination motor controller, where a separate overload relay handles the thermal side. Installed as a branch device on its own, it leaves the load with no overload protection whatsoever.

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.
