4.3.6 Shunt trip control circuit
-S2
• The closing STOP signal is provided for resetting K2 on the SU-control circuit. It effects with priority in switching
OFF (by ST or UVR) before switching ON. Once switching ON and OFF signals are simultaneous, switching OFF
command will stay longer, than switching ON. It means, that OFF command is a master command.
• The coils energize for short time only. After main contacts opening, switch HS 11 and HS12 cuts off both trips.
• Manual closing of the breaker, while –S2 contact is closed, leads to overheating of ST coils and its damage.
