A transformer with a molded case circuit breaker is provided to separately block damage of the transformer and line accidents by blocking a short of the transformer through a current limiting fuse and blocking over-load and a short of a low voltage line through the circuit breaker. A transformer includes a body(100), a plurality of super high voltage bushings(200), a current limiting fuse, a coil unit, and a molded case circuit breaker(500). The body(100) has insulating oil inside. The super high voltage bushing(200) is a load-break connector of a plug-in type which breaks a load during conduction, is installed at an outer wall of the body(100), and receives super high voltage from a power supply system. The current limiting fuse is installed in the body(100), and one end thereof is connected with the super high voltage bushing(200). The coil unit is installed in the body(100), and a primary side thereof is connected with the current limiting fuse. The molded case circuit breaker(500) is installed at the outer wall of the body(100), and one end thereof is connected with a secondary side of the coil unit.
