Monitoring relay CRGF1-18

• monitors the dangerous value of the leakage ground current that can
cause e.g. undesirable overheating of cables and a subsequent failure
of the device or even dangerous voltage of the grounded device
• serves as protection of electrical engines, generators, transformers and
other devices
• continuous monitoring of the current value using an external current
shunt
• very short response time (< 40ms)
• step-adjustable value of monitored current (in 10 steps)
• step-adjustable response delay (in 10 steps)
• indication of exceeding 2 levels of monitored current (60 and 100%
Imax)
• selection of the value of a shunt on the device panel – 0.2 mΩ or 2 mΩ
• switching the relay mode on the device panel – LATCH ON or OFF
• RESET & TEST button for the return to the initial state or device test
• analogue output 0…1mA for the control meter
• 2 types according to the value of the supply voltage: 24 – 240V AC/DC
or 12 – 24V DC
• 3-module version, mounted onto the DIN rail
