One undervoltage release or shunt release can be installed for each circuit
breaker. The following voltage ranges are possible:
Auxiliary release
Undervoltage release
Undervoltage release
with leading
auxiliary contacts
Shunt release

Table 2-6: Voltage ranges of the auxiliary releases

1) Transformer operational voltage of the lower mark of the voltage range at 0.85 (Tu = 60 °C)
is valid for 100% (continuous) duty cycle only at AC 50/60 Hz
2) Transformer operational voltage of the lower mark of the voltage range at 0.9 (Tu = 60 °C) is
valid for 5 seconds duty cycle at AC 50/60 Hz and DC
