Protection Relays and Controls MOTOR AND PUMP PROTECTION - SINGLE AND 3-PHASE Bluetooth Overload Relay Description The MP8000 is an electronic overload relay that provides advanced motor protection and is fully programmable via Bluetooth* using the Littelfuse app on an Android* or iOS* mobile device. It is easy to use and shock hazard is reduced, because the app allows settings to be modified and real-time operational information to be viewed without requiring the user to open the control panel. The MP8000 protects any motor drawing 0.5-1,000 full load amperes (external CTs are required above 100 amperes). It is designed for single or 3-phase systems with operating voltages of 90-690 V ac (use of external potential transformers can extend upper voltage range above 690 V ac). For retrofit applications above 690 V ac where PTs cannot be added, the MP8000 can be set to current-only mode. Common applications include conveyor Patented systems, HVAC equipment, saws and grinders, fan motors, and almost any pumping application. Wiring Diagram Protection is unsurpassed by combining overload, over and TYPICAL WIRING DIAGRAM FOR 3-PHASE undervoltage, phase loss and reversal, voltage and current PHASEA unbalance, power monitoring, and underload protection in one PHASEB 90 - 690 V ac package. For standalone applications, the Bluetooth interface can PHASEC 0.5 - 100 A (1,000+ A using external CTs) be used when paired with a smartphone or tablet. The units also feature an Ethernet communications port that can be used to FROM A1 connect to a Modbus TCP/IP or Ethernet/IP network. Unit can be remotely monitored and controlled from a PC or SCADA system, and data logging is available through a PC with the MP8000 C software or other software using the MP8000 memory map. This capability allows for a simple cost-effective way to further reduce C PILOT START shock hazards.
