GE type HPC™ switches are UL listed in accordance with Standard 977, fused power circuit devices (UL File No. E-51827). The charge after close mechanism provides stored energy, quickmake/quick break operation. Multiple spring loaded high pressure current carrying contact arms and an arcing contact arm provide excellent current carrying capability without sacrificing high interrupting fault performance. These switches are 100% rated and can interrupt, on a make and break basis, a minimum of 12 times their nameplate rating without fuse assistance at 600 VAC. Complete HPC™ switch and Class L fuse coordination is therefore achieved for all levels of fault current up to 200000 rms A symmetrical at 600 VAC maximum. Type HPC™ switches used as service disconnects comply with the National Electrical Code Article 110.10 for adequate short circuit current and ground fault protection.

• High dielectric strength, glass reinforced insulated case
• Arc chute of unique construction suppresses arcs and cools gases rapidly, providing quick arc interruption and extended switch life
• Interphase partitions mesh with switch midcover to completely isolate each pole
• Preloaded constant pressure pivot eliminates braid whip and fraying on high short circuit currents and repeated operations
• Green (OFF), red (ON), eliminates any question about the position of the switch contacts
• Extra heavy duty, low torque rotary operated closing mechanism
• Finger tip off button instantly opens the switch contacts
• Separate fuse access door is not required
• Fuse mounting bolts with captive washers for ease of mounting fuses
• Padlocking provisions standard
• For use with ground Break™ components or for remote tripping
• Without fuses
• For resistance grounded systems or where zone selective interlocking is required, electric trip HPC™ switches with ground Break™ system components are recommended
