Rastsepitel of the minimum tension of RM-47 IEK. Rastsepitel of the minimum tension of PM47 is applied to automatic switching off one - two - three - or the quadripolar automatic switch of the BA47 series at inadmissible undervoltage.
Represents the electronic threshold element connected to a controlled electric chain. The electromagnet which via the lever influences the mechanism of dumping of independent unhooking of automatic switches is connected to an exit of a threshold element. At operation of an independent rastsepitel from the front panel the RETURN button acts. For repeated turning on of the switched-off automatic switch it is necessary to press the RETURN button before fixing. This feature of execution of a design of PM 47 allows to define the reason of shutdown of the automatic switch: emergence of an overcurrent in the protected chain or undervoltage to unacceptable value.
