Air Circuit Breaker (ACB)
An air circuit breaker is a breaker that shuts off electrical current in air in the same way as a molded case circuit breaker, earth leakage circuit breaker, or other breakers in order to protect low-voltage electrical circuits.
This breaker is used primarily as a breaker for shutting off large currents and has different performance than a molded case circuit breaker. It has excellent open/close durability and is a draw-out type that provides high maintainability.
Differences from MCCB
Draw-out type
By using a draw-out type for the ACB, maintenance is possible simply by pulling out the main body.
Tamaño
The models with 3200A or smaller frames retain the same shape as previous products but have improved performance. With the 2000/4000A frames, ACB that are smaller than previous products even with the same rated current have been added to the lineup.
Improved performance with the same size!
The sizes of the AE1600-SS (previous product) and AE1600-SW (current product) are both
height 410 mm × width 340 mm × depth 290 mm.
Furthermore
More compact! 30% smaller!

Características
Easy replacement of a previous product (AE-SS)
AE-SS production period: De 1991 a 2007
- Because the installation dimensions and external dimensions are the same as the previous product (AE-SS), it is easy to replace an old product with a new one.
- With the draw-out type, replacement together with the cradle is necessary.
- Can also be installed on an existing connecting bus bar without a special connection kit. (Except for the AE2000-SWA and AE4000-SEA)
An adapter is required to replace an AE-S model
AE-S production period: De 1982 a 1991
- A special adapter has been prepared for replacement of an AE-S model. (Only draw-out type supported.) Please contact us for details.
Reverse connections supported
- Because the main circuit terminals are the same on the line side and load side, these products can be used with both a normal connection and reverse connection.
Zero arc space
- The amount of gas ejected to the exterior of the breaker has been greatly reduced, for safer use. (AE630-SW to AE4000-SWA, 600VAC or less)
Product specifications that match a wide range of needs
- The open/close durability is excellent, the range of standard compliance is broad, and a wide variety of attachments are available.
