Air Circuit Breakers

Make electrical equipment multi-functional by means of Mitsubishi air circuit breakers that are suitable for protection of the main circuit.

Air circuit breakers have many advantages, among them adding higher reliability during switching. They can be used to extend the area of selective coordination trough expansion of the rated short-time withstand current, for use in main circuit ports.

Air Circuit Breakers (ACB) AE-SW

Air Circuit Breakers (ACB)

This kind of breaker is used as the main power breaker of the supply such as buildings, factories and ships etc. and satisfy the various needs.

The columns for “without instantaneous” are the values when the bare main body and the external relay is combined.
The number of operating cycles without rated current also include the number of operating cycles with rated current.
AE4000-SW, AE5000-SW, AE6300-SW, AE2000-SWA and AE4000-SWA apply for only vertical terminal of connecting terminal.
This value means number of operating cycles of ACB's body not including accessories.
Products with low rating types is available.
