Siemens offers various accessories to help customize the products to fit your applications.
All breaker, switch and tap box modules include (2) thru bus cover plates (cat #WMEP) meant to cover the ends of the installation. Additional cover plates are available for order if needed. For applications using a load-side tap box or breaker module an additional single bolt joint coupler is needed (Cat # SBJ1 for single phase and SBJ4 for 3 phase). Other accessories can be found on Speedfax page 2-81.
