3 phase 480v fused disconnect
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.
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.
What is a 30A circuit-lock disconnect?
HBLDS3P Hubbell’s new 30A Circuit-Lock Disconnect with integral phase indication LEDs redefines the benchmark for safety by providing insight into the enclosure while in use. Six highly visible LEDs (3 line side/3 load side) display the electrical status of the switch by phase.
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.
