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 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.

In case of circuit breaker failure or failure detection, contact the 

organizations specified below.

At the end of its service life, the circuit breaker should be disposed of.
Basic insulation is a precautionary measure for basic protection against 

electric shock, and no protection against damage is provided.

The control handle of the circuit breaker has three positions: "ON", "OFF", 

middle position. At the first turn-on and after the protective shutdown (including 
when the shunt and undervoltage release trips), to close the main contact group 
of the circuit-breaker, it is necessary to move the handle from the middle position, 
first to the "OFF" position, then to the "ON" position.

The circuit breaker design contains an in-service inspection device - the 

"Test" button, when pressing, the main contact group is reset (in this case, the 
control handle of the circuit breaker will take the middle position).

The interphase baffles included in the delivery set should be installed in the 

corresponding grooves during the installation of external conductors.

Transportation, storage and disposal

The circuit breaker is a repairable product. It is necessary to periodically 

(at least once a year) 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 recommended to perform the "on-off" operation 
8

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

breaker by pressing the "Test" button.

Transportation of the circuit breaker is allowed by any kind of covered 

transport in the manufacturer's package, which protects the packed circuit 
breaker from mechanical damages, pollution and moisture ingress at 
temperatures from minus 25 

°

C to plus 60 

°

C.

Storage of the circuit breaker is carried out in the manufacturer's package in 

rooms with natural ventilation at an ambient temperature of from 

25 

°

C to +60 

°

and relative humidity up to 50

 

% at a temperature of +40 

°

C, it is allowed to store 

the circuit breaker at a relative humidity of 90

 

% and a temperature of plus 20 

°

C.

The circuit breaker should not be disposed as household waste. For disposal, 

transfer to a specialized recycling company.
