SHOCK BLOCK SPGFCI 480V 32A   Description Special-Purpose Ground-Fault Circuit Interrupter (SPGFCI), Class C and Class D The Industrial Shock Block® SB5000 series is a personnel protection device designed to meet the requirements for special purpose GFCIs defined by UL 943C. This standard outlines GFCI classes specifically designed for use in industrial facilities. Class C GFCIs are intended to be used on three-phase systems where the line-to-line voltage is 480 V or less with a trip level of 20 mA, while Class D GFCIs are intended to be used on 600 V systems. The SB5000 includes DFT harmonic filtering, an automatic self-test feature, and is compliant to the UL 1998 Software in Programmable Components standard. Ground-Fault Circuit Interrupter (GFCI), Class A The SB5000 is available as a 208 or 240 V Class A GFCI, allowing commercial kitchens, vehicle service centers, and other non-dwelling applications to meet NEC 210.8(B) for their three-phase loads up to 100 A. Equipment Ground-Fault Protective Device (EGFPD) The SB5000 is also available with adjustable protection settings as an EGFPD. The EGFPD models can be set to trip at 6 mA or from 10–100 mA in increments of 10 mA. This offers more flexibility since GFCI and SPGFCI devices are not permitted to have an adjustable trip level. Ratings and Models The SB5000 is available for three-phase voltages from 208 to 600 V with a maximum full load current up to 100 A. The power system can be either solidly or high-resistance grounded, and the load must be single-phase or three-phase as long as the load does not require a neutral. The standard enclosure is IP 69K/NEMA 4X and outdoor rated, suitable for all industrial environments including high temperature washdown used in food production applications. The 32 and 60A models are also available in a hygienic stainless steel enclosure, with a 10 degree sloped top and FDA compliant silicone gasket, designed to facilitate sanitation in food processing facilities and the like. Grounding Monitor / Interrupter (GMI) The SB5000 also monitors the equipment grounding connection between the Shock Block and load. This is a required feature for Class C and D GFCI devices and is recommended for Class A GFCI and EGFPD devices. If the ground-return path is broken, the SB5000 will trip and provide an alarm by changing the state of the alarm contacts. This monitoring circuit requires an extra (pilot) wire between the SB5000 and the load. At the load, the pilot wire is connected to a termination device. The other end of the termination device is connected to the equipment ground (typically the enclosure)   Applications • For applications where people, electrical equipment, and water are present • Agriculture • Amusement parks • Commercial kitchens • Construction • Food and beverage • Horticultural lighting • Maintenance shops • Manufacturing • Mining • Oil and gas • Pools, spas, fountains, water features • Vehicle service centers • Water/wastewater   SB5032-201-0 | SB5000 Series Industrial Shock Block GFCI | Littelfuse
