Air Circuit Breaker
Note: If control voltage of Q, F, X is different from each other, they can be connected to different power. If model ST intelligent release is DC, it
must pass through U1 and U2 before directly connected to terminal 1 or 2.Circuit explanation for signal output
a.Broken-line parts shall be provided by customers.
b.Terminals 6# ~7# can output NC (normal close) contact if that is required by users.
c.Terminal 35# can be directly connected to power (automatic pre-storing energy), alternatively connect power after connecting NO button (manual-
controlled pre-storing energy).
In order to avoid the damage to shunt release and closing electromagnet, one group of NO (shunt release) or NC (closing electromagnet) contact
should be separately connected to the control circuit.
