S + S Disconnect switches are stocked in our Edmonton, Alberta, Canada facility.
L7 Switches for 16A to 100A
Modular Design Minimizes Inventory.
Sprecher + Schuh's L7 Series of disconnect switches incorporates modular design techniques to provide maximum functionality with the fewest number of parts. These rugged switches are compact, reliable and the ideal choice for all disconnect applications including motor disconnects.
Just the right switch for your application,
L7 Disconnect Switches are available in four frame sizes up to 100 amps. The smaller L7s come in three and six pole models, as well as three pole changeover switches.
A full complement of switch handles and accessories including auxiliary contact blocks, ground and neutral terminals make the L7 line broad enough to tackle virtually any disconnect duty.
Full range of enclosed disconnects for any job
From "do-it-yourself" to fully assembled, we offer a complete selection of three, four and six pole enclosed disconnects for any industrial application.
Meets the toughest safety standards
All switches are touch safe to IP20, while most switch handles are rated for strong water jets to IP66. Excellent making and breaking characteristics provide a level of safety that, in many cases, exceeds international standards.
Modular, flexible and easy to assemble, the versatile L7 line is fully modular. All accessories snap-on and off without the use of tools, speeding assembly. The L7's modular design minimizes inventory with features such as universal auxiliary contact blocks... virtually every block fits all frame sizes. Both metal and plastic shaft extension systems are available to accommodate most panel depths.
L11 Fusible and Non-Fusible Switching to 1200A
Suitable For Use in Service Entrance Applications,
Sprecher + Schuh's L11 series of fused and non-fused disconnect switches comply with UL98 service entrance requirements and are NFPA 79 compliant.
This family of rod-operated switches is suitable for applications that require small panel space and superior short circuit protection.
Big performance in a small package
L11 disconnects are rated up to 1200A and can be operated at up to 600V. They protect motors up to 500HP (@480V).
The L11 may be installed on circuits capable of delivering up to 200,000A of short circuit fault current, levels typically found in modern industrial facilities. These rod-operated disconnect switches also incorporate removable fuse carriers with an optional LED blown fuse indicator carrier.
This performance comes in a small package, leaving room for additional branch circuit components within the panel.
Maximum protection for downstream equipment
L11 switches are UL98 as a branch circuit protection device and are engineered to provide excellent short-circuit protection for downstream equipment.
The L11 fusible switches accept the latest small-dimension Class CC, J and HRCII fuses. This Type 2 protection limits let-through currents to levels specified for IEC equipment, and ensures that when the short circuit is cleared, the device will be operable.
Meets the toughest safety standards
The L11 offers a modular universal internal handle which provides an interlocked handle for test mode use and UL508A and NFPA 79 compliance in North America. The L11 30 and 60 amp units are equipped with removable fuse carriers which provide dead-front switch protection during fuse change-out.
Fuse carriers with LED blown fuse indicators are also available as an option on the 30 and 60 amp devices. Test mode D7 auxiliary contacts may be installed to provide test capability of control circuit without energizing the main contacts.
All of the L11 switches meet IP20 for finger-safe wiring terminals and IP30 for touch-safe fuse carriers.
