2.8 Condenser Trip Device

It is recommended to employ the capacitor trip unit for a

trip operation of the breaker when the control source is

lost in the AC control system.

The contacts B1, B2 of auxiliary relay are connected with

tripping push button as shown below. The breaker can be

opened automatically in case of power failure and

terminals 5, 7 can be used as AC power supply connecting

to the motor or closing circuit.

This device maintains the voltage for 60 seconds 
which can trip the breaker just one time.
It cannot be operated properly if used for other
purposes or if the circuit is modified without the
agreement of the manufacturer.
