An elevator shunt trip test checks the heat detector placement. It also monitors power and wiring diagram of an elevator.
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 is typically required in elevator disconnect switches to ensure that the elevator power shuts off automatically in the event of a fire, regardless of whether a sprinkler head is present. If the elevator does not have a sprinkler system, it may still be advisable to implement a shunt trip for safety compliance and to protect against fire hazards. Local codes and regulations should be consulted to determine the specific requirements for your situation.
Yes a shunt trip breaker can be activated 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.
Moulded breakers or shunt trip breakers - selection is defined by the current rating requirement.

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.
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.

shunt trip coil used to trip the breaker automatically or manually.
There are per-engineered shunt trip solutions such as the Littelfuse LPSM that have a transformer that isolates the line voltage from the control voltage. You simply wire the N.O. contact on the float in the shunt trip isolated contacts.
Yes a shunt trip breaker can be activated manually.
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.
Yes, you can. If your shunt trip is 120 volts, just get 120 volt from your panel and take it to your ansul normally open contacts than to your shunt trip braker. than when your ansul system trips it will trip your shunt braker.
Yes, a shunt trip breaker will trip if there is a loss of control power. The shunt trip mechanism requires power to function, and without it, the breaker cannot receive the signal to trip. However, in the event of a fault or overload condition, the breaker will still trip due to its internal protective mechanisms. It's essential to ensure that control power is maintained for proper operation of the shunt trip feature.
A shunt trip diagram typically illustrates the electrical connections and components involved in a shunt trip circuit, which is used to remotely trip a circuit breaker. It includes elements like the circuit breaker, shunt trip coil, power source, and control switch. The diagram shows how the control switch activates the shunt trip coil, causing the breaker to open and interrupt the circuit. For a specific diagram, it's best to refer to technical manuals or manufacturer specifications.
No, it does not have voltage in trip position.
