Selección de los elementos térmicos de la unidad de sobrecarga
Esta sección identifica las unidades de sobrecarga térmica necesarias para los arrancadores especificados en un pedido. Las tablas se basan en la corriente a plena carga del motor y proporcionan el número de catálogo para los elementos térmicos apropiados que se utilizarán en esa corriente nominal.
