The shunt should short-circuit the bell during rotary dialing, so that the bell doesn't jingle as you dial out.

In long shunt the shunt field winding is in parallel to both generator and series field. In short shunt the shunt field is in parallel to generator only.
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.
To connect a shunt circuit breaker with an emergency stop push button, first ensure that the power supply is turned off. Connect the emergency stop button in series with the control circuit of the shunt trip mechanism. When the emergency stop button is pressed, it should interrupt the control circuit, activating the shunt trip and opening the circuit breaker. Finally, verify the connections and test the system to ensure proper operation.
Because the Power Factor is over corrected.
Since the current has to supplied by the feed back circuit and current would be opposed less in shunt connection hence current feedback is done using shunt connection

The advantage of a shunt trip over an undervoltage (UVT) coil lies in its ability to provide immediate and reliable circuit interruption during specific conditions, such as remote activation or emergency situations. A shunt trip can be triggered manually or automatically, regardless of the supply voltage, ensuring that the circuit opens quickly when needed. In contrast, a UVT coil relies on a drop in voltage to operate, which may not always occur in a timely manner during fault conditions. This makes shunt trips generally more versatile and effective for safety applications.
The open-circuit characheristics and the load characheristics
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.
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.
