Magnetic starter PAE-313
PAE-313 magnetic open reversible starter without protective relay with a rated current of 40A at a voltage of 380V. Protection degree IP00. The starter is designed for remote start, stop and reverse of three-phase asynchronous electric motors with a squirrel-cage rotor operating in a temperate climate with a rated voltage of up to 380V, a frequency of 50Hz, an ambient temperature of minus 40 ° to 40 ° C. The reversible starter PAE-313 is a system of 2 conventional PAE starters and a control circuit for them, providing alternate switching on of starters and completely eliminating the possibility of their simultaneous switching on. The main contacts of both starters are connected to the phase conductors of the electrical network in such a way that when one starter is turned on, the order of the alternation of the phases of the electrical network will be different than when the other is connected. Accordingly, when one starter is turned off and the other is turned on, the order of phase alternation supplied to the three-phase asynchronous motor will change and this will lead to a change in the direction of rotation of the electric motor. PAE-313 starters are characterized by good overload capacity and therefore can be used to start electric motors with severe operating conditions and a long acceleration period and a set of rated speed. The maximum power of the controlled electric motor at the rated current of the main circuit of the starter (maximum operating current of the starter of the controlled electric motor) is 40A, at a voltage of 220V is 10 kW, and at a voltage of 380V - 17 kW. The PAE-313 starters are designed for continuous operation in intermittent modes with a frequency of up to 600 starts per hour with an on-time (DC) of 40%. For longer operating times, the frequency of starts per hour should be reduced.
