Littelfuse: Industrial Shock Block SB5000
The compact Littelfuse Industrial Shock Block SB5000 protects workers from electrical shock and is a 208 V Class A ground-fault circuit interrupter (GFCI). This allows commercial kitchens, construction sites, and other non-dwelling units with wet areas to meet NEC 210.8(B) now for their three-phase loads up to 60 A. This personnel protection device is also designed to meet the requirements for special-purpose Class C and D GFCIs defined by UL 943C for industrial facilities.
