Technical data 1156 BUSSMANN SERIES Effective December 2015 Supersedes September 2013 CUBEFuse safety switch Standard features: • Utilizing the current-limiting time-delay or fast-acting Bussmann series CUBEFuse makes it easy to precisely match the type and level of protection required, and provide Type 2 “no damage” motor starter protection when properly sized. Bussmann series CUBEFuse is available in ratings from 1 to 100 amps. • Up to 200kA short-circuit current rating to safely handle high fault current levels, minimize arc flash hazard, protect downstream equipment and help to comply with NEC® 110.9 and 110.10 requirements per UL 98 and UL 50. • Extended, clear lineside terminal shield and finger-safe 30, 60, or 100A Bussmann series Class CF CUBEFuse/CUBEFuse holder combination isolate live electrical components to improve electrical safety. • A visible double break, quick-make, quickbreak rotary blade mechanism provides positive visual confirmation of switch status for increased electrical safety. • Optional viewing window on NEMA 12 and 4X stainless enclosures provides visual confirmation that switch contacts have operated, and view fuse indication without opening the switch door. • Industry standard flange handle provides quick visual status at a glance, while the triple padlocking capability makes it easy to comply with lockout/tagout procedures. • Dual mechanically interlocked door improves electrical safety by preventing door opening when the switch is ON, or turning the switch ON when the door is open. • Available NEMA 1, 3R, 12, and 4X stainless enclosures make it easy to apply in virtually all safety switch applications. • Horsepower rated for use as a motor disconnect on single- and three-phase AC motors provides application flexibility. • Bussmann series CUBEFuse holder eliminates the need for fuse reducers, making it easy to install lower fuse ratings. • Ampacity rejecting Bussmann series CUBEFuse holder helps prevent overfusing.
