The circuit breaker allows voltage supply from the power source both from 

the side of terminals 1, 3, 5 and from the side of terminals 2, 4, 6.

 Overall and mounting dimensions of extended outputs (purchased 

separately) are shown in the figure 6.

 Recommended parameters of conductors for connection to the terminals of 

the circuit breaker are given in the table 4.

Installation rules

Completeness of circuit breaker is listed in table 5.

Completeness of set

The connection of the corresponding flexible conductors or busbars is 

carried out using the fasteners for connecting the external conductors. 
Connection of both copper and aluminum conductors equipped with lugs of JG, 
DT, DL, DTL,

 types of IEK trademark, or 

with any other, which correspond to design and cross section, is allowed. It is 
recommended to use adapter lugs together with flexible conductors (not included 
in the delivery set of ÂA88-35). The dimensions of the connected adapter lugs 
and busbars should correspond to those presented in Figures 5 or 6. The size of 
the core to be crimped (crimped) with the help of the core lug should be selected 
taking into account the requirements of 

ÂÑÍ

 13983.

Electric schematic diagram of circuit breaker is shown on the figure 3.

The normal operating position of the circuit breaker in space is on a vertical 

plane with terminals 1, 3, 5 upwards; installation on a vertical plane with the 
rotation of terminals 1, 3, 5 to the left or right by 90

°

 is allowed.

The circuit breaker is a repairable product. It is necessary periodically (at 

least once a year) to check the tightness of the connection screws. After each 
disconnection of the short-circuit current, it is necessary to inspect the circuit 
breaker and, in addition, it is recommend-ed to perform the "on-off" operation 
8

10 times without current, then simulate the automatic operation of the circuit 

The circuit breaker is installed on a metal panel with a thickness of at least 

1.5 mm or on an insulating panel with a thickness of at least 6 mm and fixed with 
the screws included in the delivery.

Additional assembly units for the circuit breakers, ordered separately, are 

shown in the table 3.  The general scheme for installing additional devices is 
shown in figure 1.

Overall and mounting dimensions of adapter lugs for circuit breakers are 

shown in figure 5 (for ÂA88-35 purchased separately).

 The minimum installation distances of the circuit breakers are shown in 

figure 7.

Time-current characteristics are shown in the figure 2.

Overall and mounting dimensions are shown in figure 4.
