Shock Block GFCI

SB5000 Series

Industrial Shock Block for Personnel Protection

*For 32 A and 60 A only

Description

Special-Purpose Ground-Fault Circuit Interrupter (SPGFCI), Class C and Class D

The Industrial Shock Block^®SB5000 series is a personnel protection device designed to meet the requirements for special-

purpose GFCIs defined by UL 943C. This standard outlines GFCI classes specifically designed for use in industrial facilities.

Class C GFCIs are intended to be used on three-phase systems where the line-to-line voltage is 480 V or less with a trip

level of 20 mA, while Class D GFCIs are intended to be used on 600 V systems. The Industrial Shock Block includes DFT

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 Shock Block is available as a 208 V Class A GFCI, allowing commercial kitchens, construction sites, and other non-

dwelling units with wet areas to meet NEC 210.8(B) for their three-phase loads up to 100 A.

Equipment Ground-Fault Protective Device (EGFPD)

Industrial Shock Block is also available with adjustable protection settings as an EGFPD. The EGFPD models can be set to

trip at 6 mA or from 10–100 mA in increments of 10 mA. This offers more flexibility since GFCI devices are not allowed to

have an adjustable trip level.

Ratings and Models

Industrial Shock Block (GFCI & EGFPD) is available for three-phase voltages from 208 to 600 V with a maximum full load

current up to 100 A. The power system can be either solidly or high-resistance grounded, and the load must be three-phase

without a neutral. The standard enclosure is IP 69K/NEMA 4X and outdoor rated, suitable for all industrial environments

including high temperature washdown used in food production.

Ground Wire (Load-Ground) Monitor

The Industrial Shock Block also monitors the ground wire (load-ground) connection between the Industrial Shock Block and

load. This is a required feature for Class C and D GFCI devices and is recommended for Class A GFCI and EGFPD devices.

If the ground-return path is broken, the Industrial Shock Block will trip and provide an alarm by changing the state of the

alarm contacts. This monitoring circuit includes an extra wire (pilot wire) between the Industrial Shock Block and load. At

the load, the pilot wire is connected to a termination device. The other end of the termination device is connected to the

load ground (typically the enclosure).
