Ground Fault Protection Products
EL731 AC/DC Sensitive Earth-Leakage Relay
The EL731 is a microprocessor-based AC/DC Sensitive Earth-Leakage Relay that offers complete coverage for all frequencies from 0-6,000 Hz. Two CT’s are required for the entire frequency range, or one CT can be used for only low-or high-frequency detection.
SE-601 Series - DC Ground-Fault Monitor
The SE-601 is a microprocessor-based ground-fault relay for ungrounded dc systems. It provides sensitive ground-fault protection without the problems associated with nuisance tripping. Ground-fault current is sensed using an SE-GRM Series Ground-Reference Module—a resistor network that limits ground-fault current to 25 mA.
EL3100 Ground-Fault and Phase-Voltage Indicator
The EL3100 is a self-powered ground-fault and phase voltage indication system for 3-phase systems. The EL3100 meets the National Electrical Code (NEC, Article 250.21(B)) and the Canadian Electrical Code (CEC) requirements for ground detectors for ungrounded alternating-current systems.
SE-704 Ground-Fault Monitor
SE-701 Ground-Fault Monitor
The SE-701 is a microprocessor-based ground-fault relay for resistance and solidly-grounded systems. In addition to common systems, it is uniquely suited for use on systems with significant harmonic content. The SE-701 can provide main-plant protection, feeder-level protection, or individual-load protection.
SB6000 Industrial Shock Block
Industrial Shock Block (ISB) 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.
Ground-Fault Circuit Interrupter (GFCI), Class AThe Shock Block is available as a Class A GFCI, allowing commercial kitchens, construction sites, and other non-dwelling units with wet areas to meet NEC 210.8(B) for their 3-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.
SB5000 Industrial Shock Block
Industrial Shock Block (ISB) is a personnel protection device designed to meet the requirements for special-purpose GFCIs defined by UL 943C.
Ground-Fault Circuit Interrupter (GFCI), Class AThe 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 60 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.
