UL 98 Non-Fused Switches

Mersen’s 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.

A wide range of ergonomic handles is available, as well as all manner of accessories,

to accommodate multiple applications.
