FAQs
For retrofit or new installations, mount the EAFR-110F on a suitable panel, connect to a 120-240 VDC or 125-250 VAC supply, and ensure 50/60 Hz operation. Utilize the current sensing input and up to three fiber loop sensors to monitor critical zones. The normally open trip contact should be wired to the protection circuit to trigger fast isolation within 2 ms of fault detection. Confirm UL/cUL labeling and maintain clear hand-off procedures for maintenance.
The device supports 80-265 Vac/dc, operates at 50/60 Hz, and provides 2 ms high-speed outputs with normally open trip contacts. It includes one current sensing input and up to four trip relays for multiple protection pathways. Power supply range spans 120-240 Vdc and 125-250 Vac, making it compatible with a wide range of industrial power systems and panel architectures.
Yes.
