TITLE

ATS46D75N ATS46D75NU Square D Altistart 46 75A 50HP Soft Starter NOS

CONDITION

New Old Stock (NOS) / New Open Box.

This unit has never been installed or placed into service. It has been stored without its original factory box and shows light cosmetic shelf wear, storage dust, minor discoloration, and small marks consistent with long-term storage.

The mounting hardware shows some minor storage-related oxidation. The main power terminals do not show obvious signs of field wiring or installation.

This unit has not been powered or functionally tested because proper testing requires qualified industrial electrical equipment and the correct control and three-phase power supply. It is being sold as NOS and untested, not as refurbished.

DESCRIPTION

Genuine Square D / Telemecanique Altistart 46 solid-state motor soft starter.

Primary model: ATS46D75N

Secondary barcode marking: ATS46D75NU

This soft starter is designed to reduce motor starting current and mechanical stress by gradually ramping a three-phase AC motor up to operating speed. Typical applications include industrial pumps, fans, compressors, conveyors, and other motor-driven machinery.

The ATS46D75N is discontinued and no direct OEM replacement is currently identified by Schneider Electric. NOS units may be useful as direct replacements in existing Altistart 46 installations where changing to a newer series would require rewiring or redesigning the control system.
