• Type-B earth leakage relay
• True RMS
• Modular DIN rail 3 modules
• Green LED (power ON)
• Red LED (TRIP)
• Red LED (Missing CT connection)
• Yellow LED (Alarm)
• CTB-2 Type B earth leakage transformer
• Provides earth fauli protection function eith two separate adjustable thresholds (TRIP and alarm), with adjustable delays
• Measures(TRMS)the residual current value, the alternating(AC) and direct(DC) component according to the standard IEC/EN 60947-2 annex M
• View the measured value via a multifunction LCD display(it changes color according to the system status
• Indicates akarms via LEDs (trip and ALARM) and changeover contacts
• Provides password protection against unauthorized parameter changes
• Residual current peak values
• Total harmonic distortion (THD) and harmonic analysis
• Stores in the memory the earth leakage current value measured for the AlARM and TRIP events detected
• Provides a self-test to monitor the toroid connection
• RS485 communication port (Modbus-RTU communication protocol)
