3RR22 Standard digital setting current monitoring relay

Connection of terminals
Depending on their design, the current monitoring relays are supplied with a 24 V AC/DC or
24 to 240 V AC/DC supply via terminals B1/B2.
The current monitoring relays monitor an AC load current (apparent current I
current I
monitoring relay has two separate outputs which respond to separate threshold values.
In accordance with the configuration the system is monitored for overshoot (I▲ CO contact,
I!▲ semiconductor output) or undershoot (I▼ CO contact, I!▼ semiconductor output), or values
are checked within a window range (I▲ , I!▲ and I▼ , I!▼ ≠ OFF).
