Schneider Electric ATS490D62Y Altistart Soft Starters (ATS01/22/48)

Razz Middle East supplies Schneider Electric Altistart soft starters across Saudi Arabia — the ATS01 compact range and the higher-power ATS22 and ATS48 ranges used to ramp motor voltage up at start and down at stop instead of switching it on and off directly. Every item is sourced to order against the reference you quote and delivered duty-paid to your site. Typical lead time is three weeks from order confirmation.

This page covers Schneider Electric part number ATS490D62Y — Altistart Soft Starters (ATS01/22/48). Quote the full part number with your enquiry and the item is unambiguous: one part number identifies one exact product variant, including options that are not visible in the description.

About Altistart Soft Starters (ATS01/22/48)

An Altistart is not a variable speed drive, and the distinction is worth stating plainly because the two are easy to confuse from a parts list. A soft starter controls only the ramp at start and stop — it raises motor voltage gradually over a set time instead of applying full line voltage instantly, and lowers it gradually on stop — but once the motor reaches full speed the starter has nothing left to do. It does not control running speed; that role belongs to the Altivar range covered separately in our catalogue.

The ATS reference identifies the range and rating. ATS01 is the compact, economy tier aimed at straightforward pump and fan starting where cost matters more than options. ATS22 and ATS48 are higher-power ranges carrying more starting and protection features — current limiting, adjustable ramp profiles, and motor protection functions that ATS01 does not offer. ATSU01 references are a further compact variant within the same logic. Rating is set by motor current and starting duty rather than motor kilowatts alone, since a heavy or frequent starting duty needs more starter capacity than the nameplate power suggests.

Altistart Soft Starters (ATS01/22/48) in Saudi Arabia

Soft starters go on large pumps and fans to avoid the disturbance a direct-on-line start causes — a voltage dip felt elsewhere on the supply, water hammer in a pipeline when a pump comes up to speed abruptly, and mechanical shock through the coupling and driven equipment. That makes them standard on utility-scale water pumping stations, desalination intakes and HVAC fan installations across the Kingdom, wherever a hard start would otherwise be a genuine nuisance.

The concern is sharper on sites with a weaker local grid connection, common on remote or desert locations away from the main network — a hard start there can dip voltage enough to disturb other equipment on the same feeder, and a soft starter is often the more practical fix. Ambient temperature affects selection too: a starter's semiconductor devices are rated against a reference ambient, and a unit at its nameplate rating in a hot, unconditioned motor control centre works closer to its limit than the datasheet suggests.

Ordering and lead time

Quote the full ATS reference from the unit label, including the suffix, since more than the current rating varies within a range. Tell us the motor's rated current and voltage and the supply voltage, because the starter is selected against the motor's full-load current rather than its kilowatt rating alone.

Tell us the starting duty as well — how the load starts, how often, and whether it is a pump, a fan or another type of load — since a starter sized for occasional light starting is not sized correctly for frequent heavy starting at the same motor rating. If you are replacing an existing unit, a photograph of the label is the fastest route to the right reference. Where an older ATS reference has been superseded we will confirm the current equivalent and flag what differs in wiring or parameters. Typical lead time is three weeks, and items are supplied to order and delivered duty-paid.

Specifications are taken from the supplier's published catalogue data. Confirm against the manufacturer's current datasheet before ordering.
