MAGNETIC MOTOR STARTERS
Non-Combination Starters to 900 HP
Built to Your Specifications and Ready to Install
Sprecher + Schuh non-combination magnetic motor starters are intended to eliminate the purchase and assembly of a separate contactor, overload relay and associated wiring. When purchased with an enclosure, the starters are mounted and ready to install on receipt.
Starting with the best
At the heart of all magnetic starters is the Sprecher + Schuh CAT7, CAT6 and CAT5 line of motor starters. These starters are compact and offer intermediate sizes to better match specific motor requirements. This equates to generous wiring space and less wasted horsepower capacity.
Magnetic starters are equipped with Sprecher + Schuh's CEP7 solid state overload relay as a standard selection. Unlike traditional overload relays that indirectly sense motor current through heater elements, CEP7 solid state overload relays measure motor current directly through integrated current transformers and on board electronics. The electronics provide numerous advantages over electromechanical relays.
The right enclosure... whatever the application
Sprecher + Schuh's broad line of IEC style starters can be purchased pre-installed in a variety of standard enclosures, and assembled in our custom panel shop. Cataloged enclosures include:
| Type 1 (M1) | General Purpose |
| Type 12 (M12) | Industrial Dusttight |
| Type 3R (M3) | Raintight (outdoor) |
| Type 4 (M4) | Watertight |
| Type 4X /(F4) | Watertight, Corrosion Resistant |
Even though these are the most popular enclosure types for most industrial applications, we can house any starter in a custom enclosure of your choosing. Sprecher + Schuh only sources enclosures from name brand manufacturers, ensuring the highest quality. We primarily use enclosures that meet UL Standards, i.e., Type 1, Type 3R, etc., however, we can also source IEC-type enclosures at your request. Enclosures are sized first to accommodate the depth of the contactor and offer sufficient electrical clearances to satisfy UL.
Add a variety of modifications
If you need a larger enclosure than what is specified in our catalog, your sales representative and our Engineering department will work with you to customize any of our enclosed products to suit your exact specifications. Any combination of enclosure types, sizes, pilot devices, meters and other modifications can be combined to provide exactly the panel you need.
