Product FAQs
7 answersWhat does the ST suffix mean on the BR230ST?
The ST suffix indicates that this breaker includes a factory-installed shunt trip. This feature allows the breaker to be tripped remotely when a voltage signal is applied.
What voltage is required to activate the shunt trip?
The shunt trip coil on the BR230ST requires a 120VAC signal to activate and open the circuit.
How many panel spaces does the BR230ST require?
This unit requires three 1-inch spaces in your load center. The 2-pole breaker occupies two spaces, and the attached shunt trip requires one additional space.
Can I add a shunt trip to a standard BR230 breaker in the field?
No. Shunt trips for Eaton BR series breakers cannot be field-installed. You must purchase a breaker with the shunt trip factory-installed, like the BR230ST.
Are Eaton and Cutler-Hammer BR breakers interchangeable?
Yes. Eaton manufactures Type BR breakers under both the Eaton and Cutler-Hammer brand names. They are fully interchangeable in Type BR load centers.
Is the BR230ST suitable for HVAC equipment?
Yes. All Eaton Type BR 1-pole, 2-pole, and 3-pole circuit breakers carry an HACR listing, making them suitable for heating, air conditioning, and refrigeration applications.
Does the BR230ST provide arc fault or ground fault protection?
No. The BR230ST is a standard thermal-magnetic breaker with a shunt trip. It does not include AFCI or GFCI protection circuitry.
