Inside of every motor control center is a collection of MCC buckets, otherwise known as wrappers.

These are the modular, partially-enclosed components of the motor control center and contain a collection of motor starters, relays, variable frequency drives or soft starters and other components that control motor-based equipment.

The large number of low-voltage MCC circuits results in significantly more human interaction time with low-voltage MCC equipment than with medium-voltage MCCs and switchgear simply due to the volume of these circuits in the market place.  Proactive maintenance indicators based on load characteristics, motor start characteristics and thermal measurements are something to monitor for a reliable MCC system. Factors like time synchronization, Ethernet-based protocols, sequence of events records, monitoring and alarming for protection functions, and other standard features in protective relays. 

The reliability, functionality, programmability, flexibility, and intelligence of an older smart MCC protection, metering, and control IEDs are something to keep an eye on and parts for these are hard to come by.  
 

Here at 3L2R we stock Allen Bradley 2100 series, Eaton / Westinghouse Freedom 2100 series, Square-D Model 3, 4, 5 and 6 and other vintage models.
 

We can professionally remanufacture these buckets or simply provide a good refurbished fully tested unit.
 

Whether you need just a fusible or a breaker type unit for isolation or programable starter, call us today to see how we can help.
