Fits Siemens 200A Panels with Horizontal-Throw main breaker and TOP LEFT mounted generator breaker OR BOTTOM RIGHT mounted generator breaker.  (The generator breaker mounting position, left or right side, is just the opposite of the standard model SM-200 interlock)
 
These are very high quality interlocks, precision machined from solid aluminum billet, not thin stamped sheet metal like others. They have a beautiful and smooth blue anodized finish like all of our standard production kits. The kit includes everything necessary to complete the installation including all hardware, the correct size drill bit, name brand thread lock compound, a full oil and water proof warning placard set, and clear installation instructions.
 
All of our interlock kits are proudly made in the USA and are guaranteed for life!
