EL731 - Sensitive Earth Fault Protection Relay
If you are looking for an economical earth fault protection relay, that provides detection from DC (0 Hertz), to 6,000Hz, then look no further. The EL731 is currently the only relay on the market, offering 24-240VDC, 110/240Vac supply voltage, 0-6kHz detection range, and AS2081-2011 compliance!
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. An RTD/PTC sensor input allows over-temperature protection. The EL731 offers metering capabilities, password-protected alarm and trip settings and optional network communications. It is used to add low-level ground-fault protection to variable-speed drives, and to dc currents.Features & Benefits
