Motor and Pump Protection Relays MP8000

The MP8000 series motor protection relay is designed to protect three-phase or single-phase motors with operating voltages of 90-690 V ac (use of external potential transformers can extend upper voltage range above 690 V ac). The MP8000 protects any motor drawing 0.5-1,000 full load amperes (external CTs are required above 100 A).

The MP8000 series provides locked rotor, overload, overtemperature, and unbalance protection. Voltage-based protection elements are standard. These relays include inverse time-over current elements suitable for overload protection, and they also provide monitoring functions. The protection is unsurpassed by combining overload, voltage, phase loss and reversal, voltage and current imbalance, power monitoring, and underload in one package.
