Industrial switchgear circuit breakers titania air circuit breaker electrical drawout acb with three pole having microprocessor based release ipr 2. Acbs are used for low voltage application below 690volts or it industry level it is called as lt application low tension vcb are used for medium voltage application such as below 33kv and sf6 circuit breakers are used in high voltage applicatio n as well as medium voltage application. Unlike a fuse which operates once and then must be replaced a circuit breaker can be reset either manually or automatically to resume.

With rated current up to 3000 a these breakers interrupt the arc in a vacuum bottle. A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit its basic function is to interrupt current flow after a fault is detected. Ge industrial s circuit breakers are now abb s circuit breakers. These can also be applied at up to 35 000 v.

Rcd residual current device rccb residual current circuit breaker. It operates in air where air blast as an arc quenching medium at atmospheric pressure to protect the connected electric circuits. Electrical drawout acb with three pole having microprocessor based release ipr 2. Range 630 a 4000 a.
