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.
