“MRM3-2I 电动机保护继电器”详细介绍

The motor protection relay MRM3-2 offers reliable protection for LV and MV motors which are ei-ther operated via power contactors or power circuit breakers.?The following functions are integrated into this relay:???? Overload protection acc. to IEC 255-8 in consideration of the initial load factor???(thermal image)??? Definite undercurrent protection??? Definite time over current protection (DMT)??? Inverse time over current protection (IMT) with select-able trip characteristics?? Short-circuit protection??? Load unbalance supervision with definite or inverse trip characteristics??? Earth-fault detection with suppression of harmonics??The MRM3-2 recognizes the “Start-Up“ and “Motor Running“ phase.?Motors with a limited number of starts can be controlled by the start limiting function of the relay.??The earth-fault supervision is either realized in Holm-green connection or by means of a core-type?current transformer.?
