Single, two, three and three relative ground variants for short circuit and ground fault protection

• Independent measuring element; In use, start-up and tripping instructions for each stage

• Test switches, DC/DC converters and heavy-duty trip relays are available as specified options

• Microprocessor-based time overcurrent relay with continuous setting of current operating value and delay

• Three current range variants with a wide range of Settings

• Low setting level 0,015-0,65 A or 0, 075-3,25 A or 0,375-16,25 A

• High setting stage or 0,02-8 A 0,1-40 A or 0,5-200 A and ∞*)*)16 2/3 Hz Alternative version 0,075-40 A or 0,0375-200 A and ∞

• The low setting phase can be programmed with the following time characteristics:

- Normal inverse

- Quite the opposite.

- Extreme Inverse

- ri Indicates the inverse time

- Long reverse

- Determined time delay can be set from 50 milliseconds to 8,1 second

• Optional filter with different frequency characteristics in 0, 2A variants

- 50-60 Hz sharp

- 150-180 Hz sharp

- 40-2000hz Flat 1a and 5a variants

- 50-60 Hz sharp

- 150-180 Hz sharp

- 40-2000 Hz level

- 16 2/3 Hz flat

• The high setting phase can be delayed to 1 second for selective fuse coordination

• The reset ratio of 95% brings the setting close to the maximum load current

• Recovery time < 40 ms makes time select a small time step between protection

• Low transient overreach, i.e. the relay is insensitive to DC elements in the fault current. RXIDG 21H relays and components

• The method of selective sensitive grounding fault protection in grounding systems is developed
