A secondary shunt releases (extra trip coil) is used forelectrical tripping of the circuit breaker by protectiverelays or manual control devices when more than onetrip coil is required.
A shunt-trip coil is a built-in component of a shunt-trip circuit breaker. It is a magnetic coil that can be energized externally to make the breaker trip to shut off the flow of current. For instance, fire sprinklers are sometimes required in the top of elevator shafts in case of a fire in the shaft. If the sprinklers were to spray water on the electric controls in the elevator cab, people could be hurt or killed, either from electrocution or from the elevator malfunctioning. In these cases, a shunt-trip breaker is installed in the circuit feeding the elevator controls, and the fire alarm system sends a trip signal if it detects waterflow from the sprinkler system. This trips the breaker and removes power from the elevator cab. Once tripped, a shunt-trip breaker requires a person to reset it manually.
A shunt trip breaker is reset the same way as an ordinary breaker, move the handle to the full off position and then to the full on position. First check the tripping circuit, sometimes a latch relay is used to hold the breaker shunt trip coil in the trip position. If this is the case then reset the latch relay first.
It depends on what part of the world it is in and what the usual control voltage is in that part of the world.
A shunt capacitor creates a low resistance path in a circuit so that electricity can pass around to another point. Shunt capacitors create shorts when they receive abnormally high amounts of voltage to correct series circuits.

Yes, but you need a power source, for the shunt trip coil voltage, in the circuit.
The cost of a shunt trip breaker depends on the amperage and number of poles the circuit connected to it needs. The cost of the shunt trip over a conventional breaker is substantially more.
It works just like a normal circuit breaker with one additional function. A shunt-trip breaker also has a built-in magnetic coil that can be energized externally to trip the breaker. For instance, fire sprinklers are sometimes required in the top of elevator shafts in case of a fire in the shaft. If the sprinklers were to spray water on the electric controls in the elevator cab, people could be hurt or killed, either from electrocution or from the elevator malfunctioning.

I can only assume that you are attempting to connect 480VAC coil from a elevator to a fire system in order to shunt the elevator. In order to do this you will need a shunt trip breaker rated for this use.

A shunt-trip breaker trips when voltage is applied to the coil. It does not self-reset when the voltage is removed, the breaker must be reset manually. The trip voltage can either latch or be applied momentarily, but must be de-energized before the breaker will reset.
