Communication Interfaces - Siemens SIPROTEC 4 User Manual

*) UL–listed with the Following Nominal Values:
**) UL–listed with the Following Nominal Values:
1) FLA = "Full Load Ampere"
2) High-duty relays are used for the direct activation of motor-driven switches. The high-duty relays operate in
an interlocked mode, i.e. only one binary output of each pair of switches is activated, thus avoiding a short-
circuit of the power supply. When used as a standard relay, only one binary output of a pair can be used.
Permanent operation is not specified.
