Sprecher + Schuh’s broad line of general purpose contactors combine performance and reliability in space saving designs that are well proven and used the world over. Sprecher + Schuh’s IEC design is dimensionally among the smallest devices in the industry. A range of definite purpose contactors is also available, providing reliable and economic performance in commercial applications.
Unique to IEC-style contactors is the ability to select the exact device required for a specific application. By identifying the conditions under which the contactor will be used, i.e., resistive loads, reversing, inching and plugging, etc., published “life-curve” data predicts contact life in millions of operations. This information enables you to select the precise contactor for your application… without buying too much or too little.
Destructive electrical arcs are common when opening or “breaking” the contacts of larger contactors. Sprecher + Schuh contactors in this size class are designed to dramatically reduce electrical arcing by quickly guiding the arc off of the contacts and into specially designed “arc chutes.” This special design divides and eliminates the electrical arcs quickly, significantly increasing contact life and assuring reliable operation.
All Sprecher+Schuh IEC contactors are UL Listed and CSA Approved. They also carry the CE Mark and meet IEC 60947-1 requirements. They are approved in virtually every international market.
