SEL MOTORMAX

The motorMAX Low-Voltage Motor Management and Protection System is the SEL smart motor control system for low-voltage motor control centers (MCCs). This scalable system includes protective relays, managed network switches, real-time automation controllers (RTACs), precise time sources, and machine interfaces for local and remote visualization and control.

Seamless integration with the SEL powerMAX Power Management and Control System allows operators to manage a facility’s power system, including end devices, from a single HMI screen.
No programmable logic controllers (PLCs), associated wiring, pushbutton controls, or interposing relays minimizes interconnect cabling.
Arc-flash detection (AFD) increases safety by reducing incident energy. All incoming breakers are signaled to trip in <16 ms after an arc event anywhere in the MCC.
SEL-849 Motor Management Relays and SEL-751 Feeder Protection Relays provide more data than traditional MCC components, which gives a better insight of end devices’ operation.
By using SEL components, the system can achieve higher safety integrity level (SIL) ratings.
Oscillography and Sequence of Events (SOE) recording enable online diagnostic analysis.
The delivery method reduces the time and cost of installation, startup, and maintenance.
