When Water, Power, and People Mix—Let Shock Block® Take the Hit
Industrial electrical safety just got a serious upgrade. The Littelfuse Shock Block® SB5000 Series, a trusted name in personnel protection, is built for demanding environments where water, electricity, and people converge—and it’s also available in rugged stainless steel models for industries that require hygienic or hazardous-rated solutions.
What Is Shock Block SB5000?
The SB5000 is a UL-listed Ground-Fault Circuit Interrupter (GFCI) and Special-Purpose GFCI (SPGFCI) designed to safeguard personnel in high-risk environments. It’s ideal for three-phase loads up to 600V and 100A, and offers:
- Class A, C, and D GFCI protection
- EGFPD models with adjustable trip levels (6–100 mA)
- Ground-monitoring that trips if continuity is lost
Why Stainless Steel Stands Out
For industries that demand durability and sanitation, the stainless steel SB5000 models deliver enhanced performance where it counts. They feature:
- AISI 304 stainless steel enclosure with a 10° sloped top to shed water
- FDA-compliant blue silicone gasket for hygienic areas
- IP69K / NEMA 4X ratings for harsh washdown conditions
- Optional Class II Division 2 rating for hazardous environments like grain or chemical processing
These models are ideal for food and beverage, pharmaceutical, and agricultural facilities—offering the same proven protection in a design that withstands the elements.
