EL731-00-00

EL731-00-00 is an EL731 series microprocessor-based AC/DC sensitive earth-leakage relay. A RTD/PTC sensor input allows over-temperature and under-temperature protection for a motor or drive. The EL731 offers metering, password-protected alarm and trip settings and optional network communications. It is primarily used to add low-level ground-fault protection to variable-speed drives and to dc circuits.

• Adjustable trip setting provides a wide range of low-level protection and system coordination
• 32-char OLED display: earth-leakage metering, setup and programming
• Local LED indication: visual trip, alarm, CT connection indication
• CT-loop monitoring: proactively monitors for open- or short-circuit CT wiring
• Adjustable trip delay for quick protection and system coordination
• Alarm and trip settings: detect a deteriorating condition before damage occurs
• Three programmable outputs for tripping or alarming on leakage current, high, or low temperature
• Universal power supply: provides flexibility for numerous applications
• UL Listed (E340889), CSA, RCM (Australia) approved, 5 years warranty
• 120/240V AC/DC control power
