Square D by Schneider Electric 8536-SD01S Starter

Square D by Schneider Electric 8536-SD01S Starter is a NEMA Type S motor starter, Series A, Size 2, designed to start and protect a three-phase motor in a compact, panel-mount arrangement. This 3-pole, nonreversing starter belongs to the 8536 family and provides a dedicated control path for the motor with a separate control circuit. In the Size 2 class, it is rated for 15 HP at 230 VAC and 25 HP at 460 VAC in 3-phase service, with a current rating of about 45 A and a short-circuit current rating (SCCR) of 5 kA, enabling reliable protection for typical motors up to those levels. The unit is offered in an open configuration suitable for mounting inside electrical panels or enclosures and is compatible with standard accessories in Schneider Electric’s 8536 lineup, including enclosures and mounting kits for NEMA 1 protection. As a nonreversing starter, it provides straightforward on/off control of the motor via a control circuit that energizes the coil to close the main contacts, enabling safe and predictable motor starting in industrial equipment such as pumps, fans, and conveyors.
