ATC Diversified Mpa2-480-Ct replacement part, motor protection analyser 440/480 vac ext. c/t, ATC motor protection industrial control

ATC Diversified Motor Protection Analyser (MPA2 series) for three-phase motors. An all-in-one protection relay that monitors phase voltage, phase current, phase loss, unbalance, over/under voltage, and locked rotor conditions providing comprehensive motor protection from a single device.

⚠ Installation Note

Ensure the MPA2 input voltage rating matches your supply. For high-current motors, use the external CT (MPA2-CT) model do not exceed the built-in CT rating.

🔍 Application & Benefits

✖ Problems It Solves

  • ✖ Repeated motor failures from phase faults or voltage problems
  • ✖ No comprehensive motor protection in an existing control panel
  • ✖ Multiple separate relays needed for phase, current, and voltage protection
  • ✖ Motors failing from locked rotor conditions without protection

✓ Key Benefits

  • ✓ Combines phase, current, voltage, and thermal memory protection in one device
  • ✓ Eliminates need for separate phase monitor, overload relay, and current monitor
  • ✓ Integrated trip logging for diagnostic review after a fault
  • ✓ External CT input available for high-current applications
  • ✓ LED fault indication identifies the specific protection function that tripped

🔧 Installation Overview

  1. Mount MPA2 in control panel on DIN rail
  2. Connect three-phase supply to voltage monitoring inputs
  3. Pass motor current conductors through built-in CT or connect external CT
  4. Set current, voltage, and unbalance trip thresholds
  5. Wire output relay contacts into motor starter control circuit
  6. Apply power and verify all three phases read correctly
  7. Run motor at normal load and confirm no false trips before putting into service

❓ Common Questions

Q: What is thermal memory in a motor protection relay?

A: Thermal memory tracks the accumulated heat in the motor winding based on operating history. If a motor trips on overload and the protection relay is reset immediately, thermal memory prevents restarting until enough time has passed for the winding to cool preventing damage from rapid restart after a thermal trip.
