Introducing the SB6100 Industrial Shock Block®

The Industrial SB6100 Special-Purpose Ground-Fault Circuit-Interrupter (Special-Purpose GFCI) is the first UL 943C listed device that provides personnel protection for three-phase 208, 240, 480 and 600 V loads.

  • Protects personnel from electrical shock where standard GFCI breakers and receptacles are not available
  • Offers an all-in-one solution to detect leakage current and interrupt the power for loads up to 100 A
  • Includes overcurrent protection provided by Littelfuse Class T fuses, eliminating the need to install separate contactor protection, saving cost and space while also allowing for a short-circuit current rating (SCCR) of 50 kA
  • Monitors the continuity of the ground circuit to ensure equipment is properly grounded
  • Prolongs the life of the internal contactor by offering undervoltage, brownout and chatter detection
  • Is available as a GFCI, Special-Purpose GFCI, and equipment ground-fault protective device (EGFPD)
  • GFCI models have a fixed 6 mA trip level (Class A)
  • Special-Purpose GFCI models have a 20 mA trip level (Class C and D)
  • EGFPD models can be set to trip at 6, 10, 20...100 mA in increments of 10 mA
  • Class A GFCI with fixed 6 mA trip level allows commercial kitchens and other non-residential facilities with wet areas to meet NEC 210.8(B) for 100 A loads
  • Special-Purpose GFCI and EGFPD models include CSA C22.2 No. 144-M91 certification
