Do you have to select a shunt trip coil and a shunt close coil for Masterpact NT/NW or Powerpact P when they are motor operated? It is not very clear in the product selector.Product Line:
Circuit BreakersResolution:Masterpact NT or NW (electrically operated)
In the product selector, when you choose the option "Spring Charging Motor", the shunt trip and the closing coils are not automatically included
for Masterpact NT and NW. You must select each one. You can have them all at the same voltage or different voltages. Note there is an option to add a second shunt trip, which can be at a different voltage than the others.Powerpact P (electrically operated)
In the product selector, when you choose the option "Spring Charging Motor", the shunt trip and the closing coil are automatically included
for Powerpact P. You don't select them. All three (motor, shunt trip, closing coil) will be at the same voltage. The shunt trip shown in the selector is for a 2nd shunt trip that is not involved in the electrical operation of the breaker. The 2nd shunt trip can be at a different voltage than the others.
