Description
Littelfuse® Motor Protection System, Series: MPS, 65 to 265 V AC/80 to 275 V DC, 50/60 Hz Frequency, 5NO-2NC 5 Form A/2 Form C Contact Configuration, Surface Mounting, 4.8 in H x 7.5 in W x 5 in D Dimensions
Features:
- Overload, extends motor life and prevents insulation failures and fires
- Current unbalance/phase loss/phase reverse prevents overheating and extends motor life
- Overcurrent/jam prevents catastrophic failures and fires and extends motor life
- Undercurrent detects low level or no-load conditions
- Ground fault 50G/N, 51G/N prevents catastrophic failures and fires
- Overvoltage prevents stress to insulation
- Undervoltage prevents a start attempt when it will damage the motor
- Voltage unbalance detects unhealthy supply voltage
- Phase differential provides sensitive protection for high resistance winding faults
- Dynamic thermal model provides protection through starting, running, overload and cooling cycles
- Reduced overcurrent mode minimizes arc flash hazards during maintenance
- Starter control simplifies the installation by reducing component count
- Metering displays the measured and calculated motor parameters
- Data logging onboard 64-event recorder helps with system diagnosis
- Communications remotely view measured values, event records and reset trips
- Internal circuits are conformally coated to protect against corrosion and moisture
- RS/TIA-485 communications
Applications:
For used to provide protection for 3-phase low and medium voltage, medium to high horsepower induction motors
Standards/Approval:
- cCSAus File No. LR62897
