The magnetic circuit breaker has ______ trip action.

  • The magnetic circuit breaker has Instantaneous trip action.
  • Magnetic circuit breakers are designed to protect electrical circuits against overcurrent conditions by tripping the circuit when the current exceeds a certain level.
  • Magnetic circuit breakers have an instantaneous trip action, which means that they can trip the circuit within a fraction of a second when a short circuit or other high-current fault occurs.
  • The instantaneous trip action is provided by a magnetic coil that is wound around a core inside the circuit breaker.
  • When the current flowing through the circuit exceeds a set limit, the magnetic field generated by the coil becomes strong enough to pull down a trip bar or latch, which interrupts the circuit and shuts off the power.
  • In addition to the instantaneous trip action, magnetic circuit breakers may also have thermal trip elements that provide protection against overloads.
