Littelfuse MPU-32-02-01 Motor Protection Unit
Brand: Littelfuse
Part Number: MPU-32-02-01
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
Additional Description: LTFS-MPU-32-02-01 MOTOR PROTECTION UNIT 1A DEVICENET
Catalog Description: The MPU-32 Motor Protection Unit is used to provide currentand temperature-based protection, metering, and data logging for three-phase low-voltage medium-horsepower induction motors. This relay is ideal for retrofitting and upgrading obsolete or aging motor protection using existing CTs. See the PMA Family of Panel Mount Adapter Kits to replace common obsolete relays.
MPU-32-02-01 Application
For retrofitting and upgradingMPU-32-02-01 Item 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, DeviceNet communications
