The automatic ASCO switch of a series 300 in the case, 400A
It is the uniform device and is not either a contactor, or the introduction automatic machine or their combination. The design of the switch represents the mechanism of cross over type (not on contactors!), which structurally exclude a possibility of counter inclusion of the main and reserve inputs. At a deviation of indicators of tension or frequency of an external power network (time of a delay, value of parameters can be determined), ASCO switches load of food from reserve input or DG. During switching, in the presence of two sources, loading remains deenergized only 35 milliseconds.
AUTOMATIC ASCO SWITCHES
ASCO switches are the standard in the industry. Instant switching of loadings between alternative power supplies, irrespective of the size of the consumed current, is reached due to use of the reliable, checked in work one-solenoidal mechanism .
In combination with microprocessor management switches provide the most perfect method of switching even of such "difficult" loadings as engines. Only ASCO switches are really on-off switches with switching blocking. Wide range of the switches calculated on current from 30 to 4000 is issued And. Switches can have the case or be issued in packageless execution at a wide choice of the additional equipment.
