Non-fusible disconnect switches are listed to UL 98 and bear the CE mark as conformance to IEC 60947-
3. They are “service entrance” devices that are capable of fully rated load-break and load-make. All
switches over 100A have windows to provide visual indication of the contact status. Engineered to have
the smallest footprint, these switches also employ a modular design that enables the handle to be
placed amongst the poles or at the ends.
