面向商业和工业应用的GFCI和SPGFCI
阅读有关UL合规性、GFCI等级以及Littelfuse SB6100 GFCI与SB6100 EGFPD之间差异的专家解答。
损坏的“工作接地”引线或设置不当可能会使焊接电流通过设施结构、接地导体和导管配件。当这种杂散电流流经导管或控制面板时,会导致导体升温并熔化绝缘层。使用SB5000内置的接地监测,确保有效的接地故障电流路径保持完整,并主动预防未来发生电击危险。
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.
