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.
- A shunt trip works by creating a secondary circuit in a breaker to switch off the supply voltage/ current to the application. In my case the breaker shunt shuts off a supply to a chiller.
-Make sure you have the correct shunt for the correct breaker with the correct voltage for the coil. From there you can run an active from your bus bar into single or 2 pole breaker and from the breaker to a nomally open emergency stop button and from the e-stop button to the shunt and from the coil to line 2 or neutral.
-To test the shunt all you need to do is switch on the application and hit the e-stop button and that will switch off your supply to your application.
Takecare
send the 120v or what have you to a single pole switch and turn tha switch on buddy and your good to go...
A short, which will trip the main breaker.
The trip coil has the whole circuit load amperage flowing through it. Thepurpose of the breaker is to only allow current up to its trip point. That is the only way that the breaker can sense if the current is within the limit rating. If the circuit load amperage becomes greater that the breaker rating it will trip. The trip coil that you refer to is a magnetic trip which senses the magnetic field that surrounds the wire. Breakers also have a thermal trip which senses a heat build up on the current flowing through it. If the breaker is in a high ambient temperature it will lower the rating on the breaker.
A circuit breaker will trip if it is faulty or if the connected circuit has a short circuit or a connected device is trying to draw more current than the breaker rating. If you disconnect the output wire from the breaker and it still trips, it is a faulty breaker. If the breaker is tripping immediately when it is turned on then start disconnecting elements of the circuit to see what might be causing the problem. If everything was working and now isn't, it is likely that the wire from the breaker is nicked where it exits the box and is shorting to the feedthru connector.
A circuit breaker protects the wires that the devices are connected to. If the devices that are connected to the circuit are 20 amps the wire size should be #12 wire fed from a 20 amp breaker. This breaker should not trip unless the circuit is overloaded or a fault occurs on the circuit. If the devices that are connected to the circuit are15 amps the wire size should be #14 wire fed from a15 amp breaker. This breaker should not trip unless the circuit is overloaded or a fault occurs on the circuit. Putting 20 amp sockets on this 15 amp circuit will work but the circuit is limited to the amount of load that can be plugged in. You will not get the full capacity of the 20 socket because the breaker will trip at 15 amps.
If you connect the ground wire to the hot wire it will trip the breaker. If you get the white and black wires reversed it will still work but does not meet code.
You would need to take the "input" wire for the shunt trip breaker to an electrical switch (not alarm initiating switch, which are DC voltage rated) within the Automan unit and connect to the "Common" connection and the "return", the wire to the actual shunt circuit of the breaker, from the "Normally Open" connection of the switch. When the unit activates, the switch will be placed into "Closed" position, therefore completing the circuit and activating the shunt coil.
the easiest way to tell, is the shunt trip breaker will actually take up 4 spaces in your panel. the 4th space will have a neutral wire coming out of it, along with a lug for power INPUT. when voltage is applied to the shunt trip, it will cause the other 3 poles to open by tripping the breaker.
The white wire would go to the neutral bar. Just be sure of the shunt trip voltage required for the breaker and land the white wire on the appropriate neutral bar in the correct panel.
Connect to the circuit neutral wire which should also be white.
Ground fault breakers monitor the current on the neutral wire flowing back to the neutral bar, a 4 to 6mA difference will trip the breaker, Shunt trip breakers on the other hand can be tripped remotely from some other type of switch or location. In industrial applications it is used to shut power off in an emergency situation, when access to an electrical panel may denied.

As a range is a high current device, the electrical code stipulates that it has to have its own breaker. The breaker protects the wire feeder. An electric range breaker is set to trip at 40 amps. Using a smaller wire that #8 is not allowed as their ratings are below that of the #8 wire. #10 wire rating is 30 amps, #12 wire rating is 20 amps, and #14 wire rating is 15 amps.
since circuit breaker consists of coils they get heated up when high current flows, when this happens the coil get energised and pull the moving contacts to open thus the circuit breaker opens when high current flows.

A short circuit. If things are working as they should breaker will trip or fuse will blow.
