Detailed Description

• Product Type: Eaton Molded Case Circuit Breaker (MCCB), standard frame, rated for 2000 A current in a 3-pole configuration.

• Interrupting Capacity: Capable of interrupting fault currents up to 65 kA at 480 V .

• Mounting Style: Designed for door-over (D/O) mounting, meaning the operating mechanism is accessible through the panel door—enhancing safety and convenience.

• Trip Unit: The model uses the Digitrip 520Mi-LSIG trip unit, which supports comprehensive protection functions:

  • L – Long-time (overload protection)

  • S – Short-time (time-delayed short-circuit protection)

  • I – Instantaneous trip (for very high fault current)

  • G – Ground-fault protection

• The suffix “Mi” indicates IEC-compliant design of the trip unit (“i” suffix), and the “M” further defines variant/configuration with specific voltage and control options.

• Framework Context: This breaker is likely part of Eaton’s Magnum series of low-voltage power circuit breakers, known for compact design, high interrupting rating, excellent safety, and coordination features like Zone Selective Interlocking (ZSI) and arc-flash reduction.
