Requirements
When the protection relay is operating under conditions specified below (see also
“Technical data”), the relay is practically maintenance-free. The relay includes no
parts or components subject to abnormal physical or electrical wear under normal
operating conditions.
Environmental conditions
•
Specified ambient service temperature range
-10...+55 °C
•
Temperature influence on the operating values of the relay
within the specified ambient service temperature range
0.1% / °C
•
Transport and storage temperature range
-40...+70 °C

Configuration
Setting and connection example
The appropriate configuration of the output contact matrix enables using the trip
signals from the over- and undervoltage stages for operating two different circuit
breakers. The start signals can be used for blocking co-operating protection relays,
for signalling and for initiating autoreclosing.
Figure 1.3.-1 represents the relay with the default configuration.
