Single phase fused disconnect switch
What is a non-fusible disconnect switch?
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.
What type of disconnect switch do I need for my application?
You need a range of disconnect switches for your industrial control requirements ranging from “Service Entrance Rated” to mo- tor isolation. You need DIN-rail and direct mountable disconnect switches that conform to today’s “finger-safe” IEC standards. You need a range of handles, shafts and accessories to select from.
How many volts can a motor disconnect switch handle?
Capable of making or breaking loads up to 600V (UL), it is suitable as a motor disconnect. Extremely compact and robust, these switches have a variety of mounting options including DIN-rail, base, or door-mounting. A wide assortment of handles, shafts and accessories are available to accommodate any installation requirement.
When are disconnect switches used with the loadbuster tool?
When used with the Loadbuster tool, the disconnect switches are suitable for these single-phase live-switching duties on single-phase or three-phase circuits of overhead distribution systems through 34.5 kV:
