Shunt trips are devices used for the remote
instantaneous opening of the air circuit
breaker. They are generally controlled trough
an N/O type contact. The actual offer of
shunt trips proposes two supply voltages
(110 V and 220 V), both compatibles with AC
and DC currents. The shunt trips are already
equipped with a special fast connector, to
be directly inserted into auxiliary contacts
block. An auxiliary contact is connected in
series with the coil, cutting off its power
supply when the main poles are open.
