FAQs

For installation in hazardous locations, ensure the enclosure and mounting meet Class I, II, and III requirements as listed (per NEC/CEC standards) and select a location with proper area classification. The GFS1 is factory sealed and constructed of copper-free aluminum, which supports corrosion resistance in harsh environments, while its dimensions simplify panel integration and reduce space planning time.
The GFS1 provides a 20A amperage rating with a 5 mA ground-trip current at 125 Vac, enabling fast fault interruption with minimal nuisance trips. This combination improves personnel safety while protecting sensitive equipment. Its explosionproof construction and hazardous-location ratings ensure reliable operation under challenging conditions such as chemical processing or mining environments.
Yes. The GFS1 supports NEC/CEC standards and Hazardous/Classified Locations area classifications, including Class I, Division 1 and Division 2, Class II, and Class III ratings, with corresponding NEMA protections (3, 7, 9, 12). This alignment simplifies design verification and procurement for code-compliant control systems in hazardous industrial settings.
The GFS1 carries NEC/CEC compliance with Hazardous/Classified Locations designations and provides Canadian certifications via UL-listed references in the product literature. This supports cross-border deployments and ensures that installations in Canada and other regions meet recognized safety and performance requirements.
The GFS1 reduces maintenance costs through factory sealing, copper-free aluminum housing, and rugged construction that resists moisture and dust ingress. The 5 mA trip threshold provides reliable fault detection, minimizing downtime due to electrical faults. Together with streamlined documentation and installation, these factors translate to improved uptime, lower lifecycle costs, and faster project turnarounds.
