Series L7 Motor Disconnect Switches (to 315A)
Sprecher + Schuh's larger L7 Motor Disconnect Switches extend your range of applications up to 315A. These sturdy switches are compact, reliable and the ideal choice for the rigorous demands of motor disconnect switching.
Flexible switch choices
Two frame sizes provide a range of disconnect switches rated from 125 to 315 amps. Base and panel mount switches are available in both three and four poles. In addition, all switches are available with either box lugs or bolt-on terminals. Box lugs are typically used in most applications, however, bolt-on terminals may be preferred in this size switch, particularly in applications where vibration could loosen connections.
Convenient accessories
Base mount L7 switches come standard with a 195mm (7-3/4") metal shaft which can easily be cut to the correct length. A longer shaft is also available. Accessories including auxiliary contact blocks, ground and neutral terminals snap-on without the use of tools. Terminal covers are also available.
Safe and reliable
High short circuit withstand capability ensures a minimum probability of contact welding. Switches with box lugs are touch safe to IP20, while all Switch Handle Assemblies are dust and splash-proof to UL Type 3, 3R, 12 (IP66). Excellent making and breaking characteristics provide a level of safety that, in many cases, exceeds international standards.
International Standards and Approvals
All Sprecher + Schuh L7 Motor Disconnect Switches with box lugs are UL / cUL Listed. L7s with bolt-on lugs are UR / cUR Recognized. All switches carry the CE Mark and meet both IEC 947-1 and 947-3 requirements. They are approved in virtually every international market.
