Direct-On-Line starting isn't the most forgiving on the grid when you kick it on, but for most constant-speed applicaion in plants or pumps it's the standard for a reason—we've shipped thousands of these SD183T3M4A units to shops where simplicity matters more than soft-start finesse.
It's basically a workhorse for 1HP up to 20HP loads, with frame sizes form 56 to 256T that bolt onto rigid bases, and you can get 2, 4, or 6 poles depending on your speed needs; the 4-pole is what most buyers go with for general industiral duty.
Service factor can be 1.0, 1.15, or custom, and insulation comes in B, F, or H class—we usually stock F because of that it handles heat better without costing a fortune, but confirm lead time if you need H class for a hot enviroment.
The ODP enclosure with IP44 protection means it's fine for clean, dry indoor spots but absolutely not suited for wet or dusty areas, and that's just the reality of an open drip-proof design—no spinning that limitation positive.
Also, color options are black or blue, and each one carries UL, CSA, and ISO9001 certs so your compliance paperwork is square; one thing you might not think to ask is that the mounting bolt pattern matches NEMA standard (56-256T), which makes swapping out an old motor pretty much plug-and-play.
We've got about 50 units or so in stock for the common 10HP 4-pole configuration, but custom insulation or a 1.0 service factor order will add 20 days or so to teh lead time—just flag it when you send the PO.
Our MOQ is typically 50 units for custom builds like a 1.15 service factor or H-class insulation. Standard models might have a lower MOQ, so let us know your specific configuration.
No, the SD183T3M4A maxes out at frame size 256T. For 20HP, that frame works fine, but if you need larger, we’d look at a different model in our lineup.
For 100 units with blue paint and F-class insulation, expect around 6-8 weeks from order confirmation. Standard black with B-class insulation cuts that to 4-5 weeks.
Yes, each motor ships with UL and CSA certification copies, plus ISO9001 quality docs. Just request them in your PO and we’ll include them in the packing.
We ship each motor in a sealed plywood crate with rust inhibitor paper and plastic wrap. Stored indoors below 90% humidity, it’s good for at least 2 years before needing inspection.
