GFCI and SPGFCI for Commercial and Industrial Applications
Read expert answers to questions about UL compliance, GFCI classes, and the differences between Littelfuse SB6100 GFCI and SB6100 EGFPD.
Damaged “working ground” leads or improper setup can allow welding current to take alternate paths through facility structure, ground conductors, and conduit fittings. When this stray current runs through conduit or control panels, it causes the conductors to heat up and melt insulation. Use the SB5000’s built in ground monitoring to make sure the effective ground-fault current path stays intact and proactively prevents future shock hazards from occurring.
Learn how the Littelfuse PGR‑8800 Arc‑Flash Relay helped a facility reduce an HRC‑4 hazard to HRC‑2, enabling safer access and preventing a near‑catastrophic arc‑flash event. Installed in just hours, it detected the fault and tripped in 1 ms—avoiding up to $1M in damage and months of downtime.
Andrew Peller Winery upgraded safety in its damp production areas by installing the Littelfuse SB5000 3‑phase GFCI. After a successful six‑month trial, the unit delivered reliable shock protection and proactive tripping, meeting all expectations. Impressed, the winery began expanding SB5000 use across its facilities to safeguard workers.
A global window‑treatment manufacturer strengthened safety beyond code compliance after surveillance footage revealed recurring arc‑flash and ground‑fault hazards. By installing the Littelfuse SB5000 GFCI on 480‑V circuits, they eliminated shock risks, prevented arc‑flash incidents, and enhanced worker protection without nuisance trips.
A global food manufacturer's fast‑changing production line required frequent equipment moves, exposing workers to shock risks from plugged and unplugged machinery. After testing a Littelfuse SB5000 GFCI, the company installed 70 units, gaining proactive shock protection, ground‑check monitoring, and reliable performance—all ensuring safer, uninterrupted production.
The City of Roswell cut risky cabinet access and error‑prone handwritten logs by adding Littelfuse MP8000 Bluetooth® Enabled Overload Relays. Techs now read and time‑stamp motor data from smartphones at a safe distance. After starting with three units on 250‑HP pumps, they added eight more and plan expansion across wells, lift stations, and plants.
