It is not recommended to use a circuit breaker as a switch when the circuit is energized. It is NOT designed to do that. It is designed to open during a current overload and will not close until it cools down and is manually reset.
When routinely forced open when energized, the contacts in the circuit breaker will become burnt from arcing; the resistance will increase; when powered, the increased resistance will cause the breaker to run hot; draw excessive current, and open prematurely.
Find the on/off switch and use that. It is designed to switch when powered and why they put one there.
