Can a shunt trip be added to QO/B or QOU breakers?

How can we help you today?

Issue:
Are QO/B and QOU breakers available with a Shunt Trip?

Product Line:
Circuit Breakers

Resolution:
Shunt trips can be factory installed only on QO/B, QO/B-SWN, and QOU by adding suffix:

1042 for 12 or 24 Vac or Vdc
1021 for 120, 208, or 240 Vac

The shunt trip terminals accept (2) 14-12 AWG CU wires. The hot and neutral wires can be connected to either terminal. The shunt trip adds an additional pole space to the breaker. If the breaker is ordered without one of those suffixes, a shunt trip cannot be added in the field.
