Description
Littelfuse® Motor Protection Unit, Series: MPU-32, 65 to 265 VAC, 80 to 275 VDC, 50/60 Hz Frequency, NO-NC (3 Form C) Contact Configuration, Panel Mounting, Wire Clamping Terminal, Onboard Display, 3.8 in H x 3.8 in W x 5.2 in D Dimensions
Features:
- Overload, extends motor life and prevents insulation failures and fires
- Dynamic thermal model provides protection through starting, running and cooling cycles
- Communications remotely view measured values and event records, reset trips and access setpoint
- Ground fault 50G/N, 51G/N prevents catastrophic failures and fires
- Current unbalance/phase loss/phase reverse prevents overheating due to unbalanced phases
- RTD temperature protection (MPS-RTD module) for high-ambient or loss-of-ventilation protection
- Phase loss/phase reverse (current) detects unhealthy supply conditions
- Overcurrent prevents catastrophic failures and fires, extends motor life
- Jam prevents motor damage by detecting mechanical jams or excessive loading
- Undercurrent detects low level or no-load conditions
- Over temperature (PTC) protection for high-ambient or loss-of-ventilation detection
- Limits the motor starts per hour to prevent overheating
- Reduced overcurrent mode minimizes arc flash hazards during maintenance
- Metering - view measured and calculated parameters with onboard display
- MPU-CIM - separate current input module to reduce risk of open-CT hazard and for convenient installation
- Analog output provides means for metering selectable parameters
- Onboard 100 event recorder for data logging
- Internal circuits are conformally coated to protect against corrosion and moisture
- RS/TIA-232, ethernet communications
