MiCOM E124 trip unit can be used in all cases where a battery and charger would otherwise be necessary to trip the circuit breaker. Such is the case in substations where there is no auxiliary supply, and where protective relays draw their auxiliary power from current and voltage transformer circuits. Thanks to the two independent set of capacitors (2*59J under 300Vdc), it allows several applications : Energize two different trip coils two consecutive trips on the same trip coil Energize a powerful trip coil (up to 118J available) In other cases where auxiliary supply is not secured or reliable, MiCOM E124 can also be used as back-up power supply during a voltage dip or an interruption of supply to prevent the device from resetting/rebooting.
