W SHORT-CIRCUIT CAPACITY 

W STRAIGHTFORWARD RETROFITTING OF ADD-ON PARTS 

Retrofitting of add-on is particulary convenient, since it is done from 

the front. With this flexibility, changes in requirement of the installation 

are easy to cater for. 

W CURRENT RATING 630 A - 6300 A 

The new MO Air Circuit Breakers fully cover with three frame size a 

range from 630 - 6300 A. 

The nominal current can be adapted step by step to the requirement 

of the plant. The lowest current of the rating plug is 250 A. and all 

this with a seting range from 0,4 to 1 x In . 

W UNIFORM DIMENSIONS 

The MO has a uniform component height and depth over it´s whole 

current spectrum. Only the component width varies with the number 

of poles and the frame size. Fixed and withdrawable versions have 

the same width. 

WTERMINATIONS 

MO Air Circuit Breakers up to 5000 a come with horizontal connections, 

and MO 6300 A with vertikal connections, as standard. The following 

termination options are available: vertical connection, front 

connections and flanged.

W ACB MO SERIES, SIZE I AND II 

W A SEAMLESS RANGE FROM 0,16 A - 6300 A 

BE 5/6, MC and MO Circuit Breakers between them, cover a rated current range from 0,16 to 6300 A. They come in 

four different classes of switching capacity up to 150 kA, i.e. they provide the safe, as well as the economical solution 

in every case, from standard applications to the most sophisticated performance expectations. 

W COMPACT STYLE 

Their compact size enables the existing mounting space to be optimally utilized, saving precious equipment fitting capacity 

in the panel. The MO, up to a rated current of 1600 A for example, can be fitted into a 400 mm wide panel section. 

Up to a rated current of 6300 A, a section width of 800 mm suffices.
