Mitsubishi Electric’s new ACB reduces installation and maintenance stress
Mitsubishi Electric has launched new air circuit breakers (ACBs) with a breaking capacity of up to 50kA.
Dubbed the AE V Series C-class, the new ACBs give users a number of built-in features that reduce the need for multiple additional accessories.
For example, when using the built-in solenoid for remote charging, the traditional motor charging devices and closing coils can be dispensed with as the breaker only needs appropriately-matched shunt trip device. This helps to eliminate additional parts that were previously required to achieve remote operation.
Ideal for commercial facilities, the universal terminals make wiring easier and more flexible, in turn, reducing unnecessary time wastage and streamlines stock holding.
Also owing to the solenoid, maintenance processes can be reduced by 30% over existing models, helping to reduce both the maintenance time and time the breaker is offline. The new design also includes a built-in drawout handle on the front, making maintenance work easier.
Furthermore, as the C-class can be ‘charged’ electronically through the solenoid the charging power can be reduced by 88% compared to spring-charge type ACBs using motor charging devices and closing coils. In addition, charging noise can also be kept extremely low, again, providing increased benefit in maintenance.
Going forward, additional high-end models in the AE V series will be released in the future. They bring the promise of network connectivity supporting users as they integrate power management into their Smart Factories and Digital Manufacturing processes. Furthermore, IoT functions and the possibility to consider new ways of access, including wireless monitoring by the users’ smart devices such as tablets and smartphones are also being planned.
