Special Purpose Ground-Fault Circuit Interrupter (GFCI),Class C and Class D

The Industrial Shock-Block is the first permanently connected special-purpose GFCI that meets UL Standard 943C Class C and Class D—designed for people protection in industrial facilities. According to UL 943C, special-purpose GFCI’s can be used in the following applications:
  • On grounded-neutral three-phase systems where voltage to ground is above 150 Vac and equipment grounding or double insulation is required by the NEC®, ANSI and NFPA 70.
  • On grounded-neutral three-phase systems where voltage to ground is 150 Vac or less and equipment grounding or double insulation is provided, but the use of a Class A ground-fault circuit interrupter is not practical.
  • Any CEC three-phase application in which a Class A GFCI is not required.

Equipment Ground-Fault Protective Device (EGFPD)

The Industrial Shock-Block is available with adjustable protection settings as an EGFPD. The EGFPD models (hardware revision 1) can be set to trip at 6mA, and 10 to 100mA in increments of 10mA. This helps reduce nuisance tripping in systems with leakage current higher than the standard 6 mA required by UL 943 Class A GFCI (GFCI devices are not allowed to have an adjustable trip level).

All ordering options include CSA certification.
