What is the short-circuit switching (making / breaking

Such circuit breakers have high carrying current rating (4 kA to 40 kA), and have a high breaking capacity (50 kA to 275 kA). They belong to the medium voltage range, but the transient recovery voltage withstand capability required by IEC/IEEE 62771-37-013 is such that the specifically developed interrupting principles must be used.

What is meant by making and breaking current capacity of a

Circuit breakers are the main making and breaking devices in an electrical circuit to allow or disallow flow of power from source to the load. These carry the load currents continuously and are expected to be switched ON with loads (making capacity). These should also be capable of breaking a live circuit under normal switching OFF conditions as well as under fault conditions carrying the
