Drawer seat on both sides of the rails, rails on the activities of the guide plate, the circuit breaker body frame on the left and right guide plate. Drawer-type circuit breaker through the circuit breaker body on the bus into the drawer seat bridge contacts to connect the main circuit. Shake the handle of the lower beam of the drawer holder to realize the three working positions of the drawer circuit breaker (there is a position indication beside the swing handle), and there are three position locks to more reliably determine the position and prevent the body from slipping.
"Connection" position: the main circuit and the secondary circuit are connected.
"Test" position: The main circuit is disconnected and separated by an insulating barrier. Only the secondary circuit is switched on, and the necessary operation test can be performed.
"Separation" position: the main circuit and the secondary circuit all disconnected. In the "separation" position To remove the circuit breaker body, you must remove the swing out of the handle.
Drawer type circuit-breakers have mechanical interlocks that allow the circuit-breaker to be closed only in the connected position or in the test position. In the middle of the connection and test can not be closed.

Structure Characteristics of Intelligent Air Circuit
Breaker(ACB)
1.
Our intelligent air circuit breaker can be of a fixed type
and draw-out type. The fixed type air circuit breaker is
installed within a special drawer to become a draw-out type
breaker. Our circuit breaker consists of a contact system,
and arc-extinguishing system, operating mechanism, current
transformer, intelligent controller and auxiliary switches,
secondary plug and socket, under voltage and shunt releases.
The draw-out type air circuit breaker has a holder that is
made up of right and left side plates, base, beams,
etc.
2. Contact system
It adopts integrated contact system, including the main
contact and arc contact. The contact is made of high quality
material, which does not lead to high temperatures even when
it is breaking short circuit current. The contact system is
of parallel connection, which reduces the electrical-dynamic
repulsion force and improves electric steadiness.
The distance between the moving and static contact is much
greater than 18mm as it is required. This is in full
compliance with safety requirements.
Note: "Trip" lock device for breaker is optional, the
isolating switch is a necessary.
3. Arc-extinguishing chamber
Each pole has an arc-extinguishing chamber, which works to
separate and isolate each electrode. The arc extinguishing
chamber is enclosed within the insulating base of the
intelligent air circuit breaker, which enforces the
mechanical strength of arc extinguishing chamber wall and
avoids breakage when it is breaking a large short circuit
current.
4. Operating mechanism: manual and automatic
mechanism
The operating mechanism is located at the front of the
intelligent air circuit breaker. It adopts a five-link, trip
free structure. It is available with energy storage. The
breaker can be closed instantly. The stored energy can be
released by a hand-operated button or closing electromagnet.
The motor driven mechanism is integrated: consists of an
energy storage shaft and main shaft which are connected with
concave and convex parts. It is easy to assemble or
disassemble.
5. Intelligent controller
6. Drawer holder
The drawer holder of our intelligent air circuit breaker
consists of right and left guide rail side plates, base and
cross arm. A boosting device and an indicator are fitted to
the base. A static contact auxiliary circuit is installed at
the top of the drawer holder. The bridge type main circuit
contacts are safety separated by a plate at the
front.
7. Three positions of the breaker in the drawer
--\"ON" position: Both the main circuit and the auxiliary
circuit are connected. The separation plate is
open.
--\"Test" position: the main circuit is disconnected. The
separation plate is closed. Only the auxiliary circuit is
connected. Tests can be made in this mode.
--\"OFF" position: both the main and the auxiliary circuits
are disconnected. The safe separation plate is
closed.
