PREVENT ELECTRICAL SHOCK IN COMMERCIAL KITCHENS

Next-Level Shock Protection

In commercial kitchens, combining wet environments, and stainless steel equipment, creates a situation where shock can occur.

Electric ranges and other equipment must be movable to meet sanitation standards, requiring plugs. Flexible cords can wear over time, increasing a worker’s risk of electrical shock.

The National Electrical Code (NEC) now requires a ground-fault circuit interrupter (GFCI). The Littelfuse SB5000 Shock Block protects employees from electric shock. It ensures code compliance for 208 V three-phase applications up to 100 A.

FAQs

What is the Littelfuse Shock Block?
The Shock Block is available as a Class A Ground-Fault Circuit-Interrupter, Class C and Class D Special-Purpose Ground-Fault Circuit-Interrupter (SPGFCI) and Equipment Ground-Fault Protection Device (EGFPD). The Class A Shock Block is tested and certified to UL 943, while the Class C and D Shock Block is tested and certified to UL 943C. The EGFPD is an equipment protection device that is tested to a combination of both UL 943 and UL 1053. The Littelfuse EGFPDs follow the same inverse time characteristics as GFCIs while also providing adjustability for applications where higher minimum trip levels may be required.
What does the Shock Block do?
The Shock Block detects leakage current and interrupts the circuit significantly reducing or eliminating the shock potential. One key part of the additional safety features mentioned earlier, is that the Shock Block also monitors the ground wire from the unit to the load for continuity. If the wire is broken or becomes loose, the Shock Block will signal an alarm and interrupt power.
What are the differences between the GFCI, SPGFCI, and the EGFPD models?
The EGFPD Shock Block is the same as the GFCI Shock Block and SPGFCI Shock Block models, except that it has variable setpoints (6, 10–100 mA in increments of 10 mA) to provide flexibility. It can provide “let-go” protection for settings below 20 mA and reduce nuisance tripping on systems with a high leakage current by selecting higher setpoints.
