Industrial shock-block GFCI
Littelfuse’s SB6100 Series Industrial Shock-Block GFCI is designed to meet UL 943C Class C and Class D and protect industrial workers against electrical shockers.
Littelfuse’s SB6100 Series Industrial Shock-Block is a ground fault circuit interrupter (GFCI) device designed to meet UL 943C Class C and Class D, allowing industrial workers to finally be protected against dangerous electric shock. If the wire is broken or becomes loose, the Littelfuse Shock-Block GFCI will signal an alarm and interrupt power. Without this feature, workers might wrongly assume they are protected even when the ground connection has failed. Even though UL requires a minimum short circuit current rating of 5,000 A, the Shock-Block GFCI device is tested up to 50,000 A. This eliminates the need for adding external fuses for short-circuit protection. The SB6100 Shock-Block GFCI is available as an open-chassis unit that is UL-recognized for installation by an OEM, or as an enclosed unit with a NEMA-4X UL-listed enclosure.
