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.

What are the functions of shunt trip coil in ACB?
shunt trip coil used to trip the breaker automatically or manually.
How much does a shunt trip breaker cost?
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.
Does a shunt trip breaker trip with loss of control power?
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.
Where can you find a diagram for load test of a DC shunt motor?
See the diagram linked below.
How do you detect if a shunt trip breaker is malfunctioning?
The way to detect if a shunt trip breaker is malfunctioning is to manually trip the breaker. The shunt is usually wired through a auxiliary relay. Make sure that before you trip the breaker that the load can be shut off without taking a production line etc. off line. Trip the auxiliary relay using a test jumper to activate the relays coil. The breaker's handle will move to mid throw and the load will disconnect from the supply power. If the breaker trips then it is working properly. If the breaker does not trip trouble shoot the circuitry that is used to trip the breaker. Usual problem is an open circuit.
What is an elevator shunt trip test?
An elevator shunt trip test checks the heat detector placement. It also monitors power and wiring diagram of an elevator.
What are the functions of shunt trip coil in ACB?
shunt trip coil used to trip the breaker automatically or manually.
Can a shunt trip breaker be tripped from to different emergency buttons?
Yes a shunt trip breaker can be activated manually.
How much does a shunt trip breaker cost?
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.
Can you use the ansul system contacts in a kitchen to break the cooking circuits with the shunt trip breaker?
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.
When a shunt trip breaker trips does the voltage remain on?
No, it does not have voltage in trip position.
Does a shunt trip breaker work from a dry set of contacts?
Yes, but you need a power source, for the shunt trip coil voltage, in the circuit.
Where can you find a diagram for load test of a DC shunt motor?
See the diagram linked below.
How do you wire a shunt trip breaker so you can test trip it?
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.
How do you reset a shunt trip breaker?
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.
What voltage feeds the coil on a shunt trip breaker?
220V
Can you use molded breakers instead shunt trip breakers for an Ansul fire suppression system?
Moulded breakers or shunt trip breakers - selection is defined by the current rating requirement.
