It works when water, electricity and people come together

December 06, 2013

Littelfuse SB6100 Series Industrial Shock-blockElectrocution killed three U.S. workers every four days from 1992 to 2010, accounting for 5% of all work-related fatalities. Workers in the process industries can finally be protected against electric shock using a reliable, UL-listed industrial GFCI, otherwise known as a ground-fault circuit interrupter, from Chicago-based Littelfuse.

Until now, ground-fault circuit interrupter (GFCI) devices have not been practical in industrial settings.

Target applications of industrial GFCI devices include electrical cabinets supplying power to pumps, washers and mixers, as well as any high-voltage machinery subject to wet conditions or wash-down cleaning. In addition, industrial GFCI devices can be mounted in movable enclosures for flexible use.

This is the first and only ground-fault circuit interrupter (GFCI) to meet UL 943C Class C and D requirements. Additional features, such as ground wire monitoring, ensure that the device operates as expected. This is extremely important, because it protects lives.

GFCI devices operate by sensing a ground fault and opening the circuit very quickly. However, residential GFCI devices are too sensitive to operate in industrial applications without nuisance tripping. The brand new UL 943C standard covers industrial GFCI devices, designed to be used with systems up to 600V and with leakage current higher than the level tolerated by residential GFCI devices.
