SB6100 Series - Ground-Fault Circuit Interrupter (GFCI) and Equipment Ground-Fault Protective Device (EGFPD)

Littelfuse Industrial Shock-Block

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

The Industrial Shock-Block is the first permanently connected special-purpose GFCI that meets UL Standard 943C Class C and Class D—designed for people protection in industrial facilities. According to UL 943C, special-purpose GFCI’s can be used in the following applications:
  • On grounded-neutral systems where voltage to ground is above 150 Vac and equipment grounding or double insulation is required by the NEC®, ANSI and NFPA 70.
  • On grounded-neutral systems where voltage to ground is 150 Vac or less and equipment grounding or double insulation is provided, but the use of a Class A ground-fault circuit interrupter is not practical.
  • Any CEC application in which a Class A GFCI is not required.

Equipment Ground-Fault Protective Device (EGFPD)

The Industrial Shock-Block is available with adjustable protection settings as an EGFPD. The EGFPD models (hardware revision 1) can be set to trip at 6mA, and 10 to 100mA in increments of 10mA. This helps reduce nuisance tripping in systems with leakage current higher than the standard 6 mA required by UL 943 Class A GFCI (GFCI devices are not allowed to have an adjustable trip level).

All ordering options include CSA certification.

FEATURES

BENEFITS

UL 943 inverse
time trip curve

Detects and interrupts to protect people and reduce the probability of nuisance tripping

Minimum trip time less than 20 msec Reduces the risk of ventricular fibrillation for leakage current of 250 mA and above

UL 943C fixed trip level
(GFCI 20 mA)

GFCI protection for systems with leakage current higher than the standard 6 mA required by UL 943 Class A

UL 943C ground
monitor/interrupt

Protects from shock by tripping if continuity of ground wire between Industrial Shock-Block and
load is broken

3 x Class T, 600 V
incoming fuses

The fuses provide overcurrent protection for a 100 A circuit and higher short-circuit rating (SCCR) of 50 kA.

Selectable trip levels
(EGFPD)
Provides extra safety when a customer is able to operate with a setting below 20 mA (GFCI) and the settings above 20 mA can reduce nuisance tripping on systems with high leakage current
Undervoltage, brownout,
chatter detection
Ensures proper operation and prolongs the internal contactor lifetime
Conformal coating Internal circuits are protected against corrosion and moisture, yet still repairable
Operator Interface Shows unit status, alarm types, and % of leakage current, and also allows for Test and Reset capabilities
