(Fuses not included) NOTE: The 800-3000 ampere integral ground fault HPC ™ switches can easily be installed in the space occupied by a manual HPC ™ switch of the same ampere rating. The 4000 ampere switch, being 3 inches wider, may require some modification. NOTE: Integral ground fault tripping is accomplished by a low-energy, flux-shifting tripping mechanism and is not suitable for remote (paralleled) tripping. If remote tripping is required, add suffix RT1 120-240Vac or RT2 480-600Vac to above product number.

HPC ™ Switches with Integral Ground Fault Protection

Integral Ground Fault HPC ™ Pick-up and Delay Time-current Curves NOTE: OBSOLETE, SEE PAGE 9-6 FOR NEW HPC ™ PRODUCT NUMBERS. 1. Mechanical Indicator – protrudes when ground fault occurs. 2. Field Adjustable Ground Fault Trip Point – from 200 to 1100 amperes in six steps. 3. Field Adjustable Ground Fault Delay Time – min. (0.03 sec.) intermediate (0.20 sec.) and max. (0.50 sec.) delay time settings. 4. No Trip Test Button – permits ground fault system check without tripping switch. 5. Test Button – simulates an actual ground fault and will trip switch off unless "No Trip" button is depressed prior to pushing test button. Ground fault indicator will protrude when system is tested or when actual ground fault occurs. Note: Although the integral ground fault function is self-powered, the test function does require an external 120Vac (200 volt amperes nominal) control power source.
