Since 1910 the name Square D has been synonymous with quality electrical equipment that withstood the test of time. In 1965 the introduction of the Type S contactor set the standard for performance and reliability. Since then the Type S line of products has continued to be the industry standard for installations requiring NEMA control. Maintaining the focus on reliability, quality and performance the Type S design covers many applications from the component level for standalone heating and resistive loads to the unlimited configurations offered in our combination motor control.
Square D Type S devices for NEMA control offer flexibility in design to meet the growing and changing industrial marketplace with a wide variety of component modifications as well as best in class engineering support system to meet customers individual needs and requirements. Robust design features and serviceable components provide longevity in product life cycles and decreased down time.
