Square D 289143BH Magnetic Motor Starter 8536 SG0

The Square D 289143BH is a full-voltage, non-reversing magnetic motor starter (NEMA Size 5, Class 8536, Type SG0, Form S) designed to start, stop, and provide overload protection for three-phase AC squirrel-cage induction motors, with a maximum operating voltage of 600 VAC. This motor starter handles continuous-duty service in demanding industrial environments and is commonly used to control conveyors, pumps, compressors, fans, crushers, and other heavy equipment within industrial power distribution systems, making it a standard choice for durable, field-serviceable motor control. Overload protection is provided by accepting compatible Square D overload relay assemblies, and maintenance teams or system integrators often choose it for replacement, upgrades, and restoration of reliable motor control in manufacturing plants, water and wastewater facilities, mining operations, HVAC, and other process equipment. For continuity and compatibility, common replacements in the same NEMA Size 5 family include Square D 8536SGO1V02, 8536SGO2V02, and 8536SGO3V02.
