A circuit switcher will be less expensive than a circuit breaker. It is commonly used for transformer primary protection.

The main negative with circuit switchers is lower interrupting rating. It also does not allow for bushing CTs.

The circuit switcher can be furnished complete with a motor operated disconnect switch.
