FAQs
For installation, mount the unit on a compatible panel, plan for 120-240Vdc or 125-250Vac power, and ensure the 50/60 Hz supply aligns with site conditions. Connect the single current sensing input and up to three fiber loop sensors to optimize fault detection. Use the normally closed trip contact to coordinate with your existing trip circuitry and establish clear interlock sequencing.
The device is designed for broad compatibility, operating at 50/60 Hz with an 80-265 Vac/dc voltage range. This enables consistent arc fault detection across mixed industrial installations, reduces need for multiple protection modules, and simplifies procurement for facilities running diverse equipment fleets.
Yes, it supports up to three fiber loop sensors to broaden fault detection coverage. It provides two high-speed outputs with 2 ms response time and includes one normally closed trip contact alongside four trip relays, enabling scalable fault coordination and fast isolation in demanding panel environments.
The EAFR-110FB carries UL Recognized and cUL Recognized certifications, ensuring regulatory compliance in North American markets. This recognition supports safe integration into commercial and industrial panels and aligns with standard safety programs in manufacturing and facilities management.
The relay enhances safety by delivering rapid arc fault detection and fast disconnection, reducing exposure for personnel. It also improves uptime through precise fault isolation, simpler wiring with fiber loop sensors, and easier commissioning, which lowers maintenance costs and supports regulatory audits in high-stakes manufacturing environments.
