The Square D 8536S Type S NEMA Non-Reversing Motor Starter delivers full-voltage starting and stopping for AC squirrel cage motors in commercial and industrial applications. This 3-pole (3P), 3-phase starter uses a melting alloy thermal overload relay for dependable motor protection and connects via screw clamp terminals for streamlined field wiring. The 8536S is offered across a Motor FLA range of 18A, 27A, and 90A, letting panel builders and contractors match overload protection to the connected motor's full-load amperage. Built on Square D's Type S platform, which spans ratings up to 810 amperes across the broader family, this non-reversing configuration is UL Listed, NEMA and CSA certified, and TAA compliant for government and infrastructure projects.

Square D 8536SBO2V03 – Frequently Asked Questions

1) How do I pick the right Square D 8536S starter for my motor's full load amps?
Pick by the motor FLA. The Type S non-reversing starters come in 18A, 27A, and 90A motor FLA ratings, ordered as 8536SBO2V03, 8536SCO3V06, and 8536SEO1V02S. Read the nameplate FLA on the motor and choose the rating at or above it; the melting alloy overload relay then has to be sized to that actual nameplate current.
2) Is the Square D Type S starter TAA compliant for a federal job?
Yes. The Type S non-reversing starter is TAA compliant and made in Mexico, which is a designated country, so it clears TAA-restricted federal, government, and infrastructure procurement. It is also UL Listed, NEMA rated, and CSA certified.
3) How does the Square D Type S non-reversing starter compare with the ABB CR306 series motor starter?
Both are NEMA-style motor starters for across-the-line motor control, but they come from different platforms. The Square D unit is a Type S non-reversing starter, 3-pole for 3-phase motors, with a melting alloy thermal overload relay and screw clamp terminals, and it is UL Listed and NEMA rated with TAA compliant construction. The ABB alternative is a CR306 series motor starter supplied as a motor control circuit component. If a drawing or an existing panel calls out Square D Type S accessories and overload heaters, the Type S starter keeps that ecosystem intact; a CR306 changes the starter family and its associated overload parts.
4) For a federally funded project with TAA procurement rules, which motor starter should be specified?
The Square D Type S non-reversing starter is built TAA compliant and is UL Listed, NEMA rated and CSA certified, which is what government, federal and infrastructure buyers typically have to document. The ABB CR306 series motor starter is listed as a motor control circuit component without that compliance statement attached, so on a TAA-restricted package the Type S starter is the one that carries the claim on its own record.
5) What is a melting alloy overload relay and how does it differ from a bimetallic one?
The overload on the Square D Type S starter is a melting alloy (eutectic solder pot) type: sustained overcurrent heats the alloy until it melts, the ratchet turns, and the contacts drop the starter out. It is a manual-reset device, so somebody has to go to the panel and reset it, which is exactly what you want where an unattended automatic restart would be a hazard. Bimetallic relays are the alternative when you need automatic reset. Changing the trip point on a melting alloy unit means swapping the thermal unit, not turning a dial.
6) Does this Square D motor starter include start/stop pushbuttons or a pilot light?
No pilot devices are included. The Type S starter ships with standard control and no control units mounted, meaning no integral start/stop pushbutton or run light. You wire your own control station, selector, or PLC output to the coil circuit, which is the usual arrangement for a panel build where the operator devices live on the door.
7) What else could I use instead of a Square D Type S motor starter?
ZenSupply also carries the ABB CR306 Series motor starter as a motor control circuit component. It is a different platform, so the enclosure prep, coil catalog numbers, and overload thermal units do not interchange with Square D Type S parts. If you are maintaining a plant already standardized on Square D Type S, staying inside that family keeps your spare thermal units and coils usable across the panels.
8) Is a NEMA starter like the Type S the right choice, or should I use an IEC starter?
NEMA starters like the Square D Type S are sized in standard NEMA sizes with generous margin and a long contact life, which is why they are specified for industrial motor control, construction, and OEM panels where oversizing and field serviceability matter. IEC devices are sized tighter to the exact motor and take less panel space. On a 3-phase squirrel cage motor that you want to start across the line with manual-reset overload protection and simple replaceable parts, the Type S is the conventional pick.
9) My motor needs to run in both directions - is the Square D Type S starter the right choice?
No. The Square D Type S starter covered here is a non-reversing configuration, meaning it provides full-voltage starting and stopping in a single direction only for AC squirrel cage motors. For a motor that must run forward and reverse you need a reversing starter with mechanically interlocked contactors, which is a different configuration within the Type S range rather than this one. The ABB CR306 series is an alternative starter family if you are specifying outside Square D.
10) Will the Square D Type S starter work on a single-phase motor?
It is built as a 3-pole (3P) device engineered for 3-phase motor circuits, so it is matched to three-phase squirrel cage motors rather than single-phase loads. Sizing is by motor full load amps, with the Type S non-reversing starters offered at 18A, 27A and 90A motor FLA ratings. For single-phase work you would need a starter configured for that duty instead - the ABB CR306 series is the other motor starter family to look at when the Square D configuration does not fit the circuit.
11) Is a melting alloy overload relay interchangeable with a solid state overload on another starter?
Not directly. The Square D Type S non-reversing starter uses a melting alloy thermal overload relay, which protects the motor through heater elements sized to the motor full load amps, and the Type S platform is offered with multiple overload relay types. A different starter family such as the ABB CR306 series uses its own overload components, so heaters and relays do not carry across between the two. Match the overload to the starter family you are installing.
12) What kind of wire terminations does the 8536S use?
Screw clamp terminals. Strip and land the conductor under the clamp, no ferrule or ring lug required, which makes field changes and re-lands on a control panel quick. That is worth knowing if your shop standard is box lug or compression, because the terminations will not match the rest of the gear.
