Frequently Asked Questions about MM300-GEHS2CAXXXX
What do the multiple "X"s in the MM300-GEHS2CAXXXX's model number indicate about the relay?
The MM300-GEHS2CAXXXX and MM300 series as a whole is built with a modular design, meaning that various functions are housed in compact, separate units called 'modules'. This reduces the amount of spare parts that may require maintenance and give users a better sense of where issues that arise are coming from. While the MM300 series can house up to eight modules, only four of the modules are integral for function and guaranteed to be included in the relay. The other four provide optional features, and the "X"s in this unit's model number indicate that the relay does not come with any of the four additional modules. Some of the elements provided by the modules include RTDs, digital inputs, phase voltage metering, phase reversal, underpower protection, and under/overvoltage protection. Users requiring any of these additional features can find other models located on AX Control's website which contain a variety of bonus modules.
