MP8000 Littelfuse 90-690VAC Bluetooth Motor Protection Relay

Littelfuse MP8000 Series Motor Protection Relay is designed to protect three-phase or single-phase motors with operating voltages of 90-690VAC (the use of external potential transformers can extend upper voltage range above 690VAC). MP8000 protects any motor drawing 0.5-1,000 full load amperes (the use of external CTs are required above 100A). MP8000 series provides locked rotor, overload, overtemperature, and unbalance protection. Voltage-based protection elements are standard. This relay includes inverse time-over current elements suitable for overload protection, and also provides monitoring functions. This protection is unsurpassed by combining overload, voltage, phase loss and reversal, voltage and current imbalance, power monitoring, and underload in a single device. Control power input for this devise is 85-264VAC. Please reference the MP800 Series product information packet for all other engineering perimeters.
