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
Listed to UL 943 and 943C for Personal Shock Protection
Commercial kitchens now have a Class A GFCI for 208 V equipment up to 100 A; for industrial applications where Class A GFCIs cannot be applied, utilize Class C & D Special-Purpose GFCI models with UL 943C Listing.
