Product FAQs
4 answersHow many panel spaces does the CH2100ST require for installation?
Due to the factory-installed shunt trip mechanism, this 2-pole breaker requires three 3/4-inch pole spaces for proper mounting in a Type CH load center.
What function does the shunt trip serve on the CH2100ST?
The integrated shunt trip allows the breaker to be opened remotely when a voltage signal is applied to the shunt trip coil. This is typically used for emergency shutdown systems or remote equipment disconnects.
Is the CH2100ST compatible with Eaton Type BR load centers?
No. This breaker has a 3/4-inch plug-on form factor designed exclusively for Eaton and Cutler-Hammer Type CH load centers. It will not fit in Type BR panels, which utilize a 1-inch format.
How does the trip mechanism operate across the two poles?
The breaker utilizes an internal common trip connection. If a fault is detected on either pole, or if the shunt trip is actuated, both poles will open simultaneously to ensure complete circuit isolation.
