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.
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.
In case of circuit breaker failure or failure detection, contact the
organizations specified below.
Connection of both copper and aluminum conductors is allowed. It is
recommended to use lugs together with flexible conductors (not included in the
delivery set). The dimensions of the connected lugs and busbars should
correspond to those presented in figures 5, 6, 7 and tables 6, 7, 9. The size of the
core to be crimped (crimped) with the help of the lug should be selected taking
into account the requirements of BCH 13983.
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 should not be disposed as household waste. For
disposal, transfer to a specialized recycling company.
Basic insulation is a precautionary measure for basic protection against
electric shock, and no protection against damage is provided.
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 40
°
C to plus 60
°
C.
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.
At the end of its service life, the circuit breaker should be disposed of.
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).
Transportation, storage and disposal
The interphase baffles included in the delivery set should be installed in the
corresponding grooves during the installation of external conductors.
Storage of the circuit breaker is carried out in the manufacturer's package in
rooms with natural ventilation at an ambient temperature of from
–
40
°
C to +60
°
C
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.
