Circuit breakers And are designed to conduct current in normal mode and the current is switched off in case of overload and short circuits, infrequent operational switching of electrical circuits, as well as for protecting electrical circuits when the voltage drops to an unacceptable value.
Machine A-3100 consists of the following main components: casing, switching devices, arc chambers, tripping over current, control mechanism and terminals for connecting the external wires.The casing is made of plastic and comprises a base on which are mounted all the parts of the machine, and cap screw to the base. The switching device consists of movable and stationary contacts. Holders movable contact connected isolated crossmember which is associated with the control mechanism. The switching contacts are made of special compositions on the basis of the silver produced by the method of the cermet. They are not welded together and operate stably without care. Filing and cleaning of the contacts is not recommended, even in cases when the surface becomes uneven, with the influx of silver. You need only look at the thickness of the cermet layer and the failure of the contacts. If the thickness of the layer or failure will be less than 0.5 mm, the machine for further work are not suitable. Interrupter chamber positioned above the contacts of each pole and operate on the principle of deionization and crushing arc steel plates.
Tripping over current is located at the bottom of the machine and its current members are a continuation of the conductive system of the machine. Tripping over current can be:
a) heat fired back with dependent current time delay with overload and short circuits;
b) electromagnetic fired without time delay short-circuit;
C) combined, fired back with dependent current time delay overload and without exposure during short circuits. Combo breakers consists of a series of thermal and electromagnetic trips.
The releases set for a certain current operation at the factory, and then sealed; operation not regulate.The control mechanism of the machine provides torque and closing the contacts, not dependent on the velocity of movement of the arm when the manual activation and torque disconnection of contacts with their uncoupling from the arm when disconnecting breakers maximum current. As the contacts are closed casing, switching position of the machine is indicated by the position of the arm: Pavluchenko position it occupies its extreme upper position in the off - bottom and off breakers - intermediate.After tripping the thermal relay machine can be enabled only when the bimetallic strip of release to cool so that will free rail trip unit. The cooling time of the thermal element does not exceed: for machines And-3160 and a-3110 - 1 min-3120-2,5 min, A-3130 - 3 minutes
