Heavy-duty starters are designed for across-the-line starting of single-phase and polyphase motors. These controls are available in NEMA sizes 0 through 6. In addition to the usual NEMA starter sizes, Siemens Furnas offers four exclusive half sizes, 13/4, 21/2, 31/2 and 41/2. These integral sizes offer the same rugged, industrial construction as our NEMA sizes and ensure efficient operating performance. Half sizes exceed the motor ratings. Features include: rugged industrial design, wide range of accessories, easy coil access, Class 48 solid-state overload relay, half sizes for cost and space savings.
