NEMA Type S motor control
Right from the start with Square D Type S motor control
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. This line of products has continued to be the industry standard for installations requiring NEMA control. Maintaining the focus on quality and performance its design covers many applications, from the component level for standalone heating and resistive loads, to the unlimited configurations offered in our combination motor control.
In the early 1930s, Square D introduced the first enclosed, combination motor controller. With application specific modifications and ongoing efforts to integrate the simple and complex product offers by Schneider Electric, we continue to maintain the customer satisfaction level Square D is known for.
Our combination solutions range from utilizing the dependable Type S motor starter with a variety of short circuit protection devices, including Class 9422 fusible disconnect switches, PowerPact line of circuit breakers, and the NEMA rated TeSys U product line.
Square D and Telemecanique are two names synonymous with low voltage magnetic control. Both now under Schneider Electric, the NEMA magnetic control offer has continued to remain as the standard over the years. From the beginning with the Square D vertical action contactor, to the current bail arm assembly, the Type S contactor has proven to withstand the test of time. Schneider Electric has also bridged the gap with our NEMA rated IEC contactor line, the TeSys N.
Square D by Schneider Electric’s NEMA manual starters and switches combine the robust standard and trustworthiness of the NEMA offer, and convenience of on-off control without the need of control voltage. Our manual control offer ranges from motor starters rated up to 10hp at 600VAC – with integral overload protection, which utilizes our melting alloy thermal elements – to our motor rated manual switches rated up to 20HP at 600VAC.
Circuit and overload protection
Schneider Electric covers all different customers’ needs by offering a wide variety of disconnecting styles; mounting types for circuit breakers, fusible and non-fusible disconnects; and a range of selectable overload protection from the industry proven melting alloy overload relay to the advanced computer management system with the TeSys T.
