Ratings and Models
The Industrial Shock Block® SB4000 series is available for use in single-phase, split-phase, three-phase and 4-wire systems from 208 -240 V on 30 A branch circuits. The power system can be either solidly or high-resistance grounded.
All SB4000 models equipped with connections for a neutral wire have built-in grounded-neutral protection per the UL 943 standard. The standard enclosure is IP 69K/NEMA 4X and outdoor rated, suitable for all industrial environments including high temperature wash down used in food production applications. The SB4000 includes advanced harmonic filtering, an automatic self-test feature, and is compliant to the UL 1998 Software in Programmable Components standard. Ground-Fault Circuit Interrupter (GFCI), Class A The SB4000 is available as a 208 - 240 V Class A GFCI, allowing new construction or retro-fit projects to meet NEC 210.8 for a wide variety of single-phase, split-phase, three-phase and 4-wire (neutral supported) loads on 30 A circuits.
