Working Mechanism

  • Eaton ED3150 circuit breaker normally passes current through its current-carrying contacts.
  • When a fault is detected, the contacts move away from each other and trip the unit thermally or magnetically.
  • After troubleshooting the issue, reset the breaker to restart the operation.

Features

  • Eaton ED3150 circuit breaker can accommodate 4 to 4/0 AWG wires.
  • This breaker features non-interchangeable thermal & magnetic contacts for long-time and instantaneous protection.
  • It has a 150A current rating and a maximum interrupting capacity of 65kAIC.
  • This circuit breaker features 3-pole, 3-phase configuration for high-speed blow open action.
  • It is equipped with bolt-on load side lug terminals for secure connection.

Standards and Approvals

Frequently Asked Questions

What is the difference between MCBs and MCCBs?

  • MCBs protect items from current overloads while MCCBs protect equipment from fault currents & excess temperature rise.
  • The tripping circuit of MCBs is fixed while MCCBs have a movable tripping circuit.
  • MCBs have comparatively low interrupting ratings than MCCBs.

What causes moulded case circuit breakers to trip?

Overloading of a circuit is the main reason that leads to frequent short-circuit tripping.

What to check before operating Eaton ED3150 circuit breaker?

  • Remove dust or moisture from the surface of the circuit breaker with a vacuum or cloth. Do not blow debris into the circuit breaker.
  • Switch to ON and OFF multiple times to ensure that the mechanical linkages are free.
  • Check base, operating handle and cover for any cracks, discolouration & chipping.
  • Check connectors and terminals for signs of overheating and looseness.
  • Check the mounting hardware and the area where it is installed.
