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
