Step down transformer circuit breaker.

They also protect circuits downstream from the transformer. Seyas 1000w auto step up step down voltage transformer converter 110 120 to 220 240 volts soft start full load 7x24hrs continous run circuit breaker protection u s. Circuit breakers protect transformers from overcurrent situations and short circuits. Us9225259 b2 4 3 out of 5 stars 439.

The lt 3000 is compatible to operate on 50 hz or 60 hz. Three phase 2 4 through 34 5 kv class 112 5 through 10000 kva 15 through 1500 kva. The 480v primary overcurrent protective device ocpd is either a thermal magnetic breaker or a set of fuses. There must be a main circuit breaker installed in a load center served by the transformer and the main breaker can be no larger than 70 percent of the maximum current capacity of the transformer.

Us9225259 b2 4 3 out of 5 stars 438. It also features the convertingbox technology which ensures lighter weight and noise reduction during operation. Once the circuit breaker opens or trips due to a short circuit or some other overcurrent scenario the circuit breaker blocks current flow to the circuit.
