Phase Monitor Relays Work For 3 Phase Systems

The selection of Macromatic phase monitor relays available through Major Electronix are designed to work with 3 phase systems. This includes both plug-in and surface mount housings, which can check for phase or voltage errors, depending on the unit. Functions such as phase loss, phase reversal, phase unbalance, overvoltage, and undervoltage are all possible options. Phase loss happens when one of the three phases is lost. Phase reversal happens when the sequence runs out of order. Phase unbalance happens when a single phase carries more or less of the load. Under or over voltage happens when the voltage for all three phases either decreases or increases at the same time.
