Littelfuse SB6100 and AC6000 Industrial Products Shock Prevention GFCI is a personnel protection device (Surge Suppressors) designed to meet the new requirements for special-purpose GFCIs defined by UL 943C. ISB is the first permanently connected Class C and Class D GFCI on the market. 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. These improvements to the standard Class A GFCI (6 mA trip level used on 240 V systems or less) were made to allow the use of GFCIs in industrial facilities. The ISB includes an automatic self-test feature and is compliant to the UL1998 Software in Programmable Components standard.
