Personnel Protection Industrial Shock Block SB5000 Series Description Special-Purpose Ground-Fault Circuit Interrupter (SPGFCI), Class C and Class D Industrial Shock Block (ISB) 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 Industrial Shock Block 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 Shock Block is available as a 208 V Class A GFCI, Simplified Circuit Diagram allowing commercial kitchens, construction sites, and other non-dwelling units with wet areas to meet NEC 210.8(B) for their three-phase loads up to 60 A. A GC K TERMINATION DEVICE L1 Equipment Ground-Fault Protective Device (EGFPD) L2 LOAD Industrial Shock Block is also available with adjustable L3 protection settings as an EGFPD. The EGFPD models can be set to trip at 6 mA or from 10100 mA in increments of 10 G G mA. This offers more flexibility since GFCI devices are not allowed to have an adjustable trip level. AUXILIARY CONTACT Ratings and Models SB5000 Industrial Shock Block (GFCI & EGFPD) is available for three- phase voltages from 208 to 600 V with a maximum full load Features & Benefits current of either 32 or 60 A. The power system can be either solidly or high-resistance grounded and the load must be FEATURES BENEFITS three phase without a neutral. UL 943 inverse time trip Inverse time detection circuit protects people while also curve reducing the probability of nuisance tripping The standard enclosure is IP 69K/NEMA 4X and outdoor DFT (Discrete Fourier Eliminates nuisance trips due to harmonics Transform) filtering algorithm rated, suitable for all industrial environments including high- Reduces the risk of ventricular fibrillation for leakage temperature washdown used in food production. A Class Minimum trip time < 20 msec current of 250 mA and above II, Division 2 option is also available for applications where Fixed 6 mA (UL 943) or 20 mA UL Listed GFCI and Special-Purpose GFCI personnel explosive dust may be present (future option). (UL 943C) trip level protection for industrial and commercial loads up to 60 A The settings below 20 mA provide extra safety. The Selectable trip levels settings above 20 mA can reduce nuisance tripping on Ground Wire (Load-Ground) Monitor (EGFPD) systems with high leakage current The Industrial Shock Block also monitors the ground wire Two-stage ground monitor Proactively protects from shock by tripping if continuity with Zener termination that of ground wire between Industrial Shock Block and load (load-ground) connection between the Industrial Shock Block meets UL 943C, CSA M421 is broken and load.
