Compact Overcurrent and Earth Fault Protection Relays
MiCOM P11x relays are compact and cost-effective solution for MV applications. MiCOM P111Enh is non-directional overcurrent and earth-fault protection housed in uniquely small case. MiCOM P115 and MiCOM P116 are self or dual powered protection relays for all MV applications where auxiliary power supply is not guaranteed. Models available: MiCOM P111Enh, MiCOM P115, MiCOM P116.
MiCOM P11x caters for applications with conventional auxiliary power and where auxiliary voltage is not available or not guaranteed by using innovative Self-Power or Dual-Power modes (MiCOM P115 and P116).
Flexible and compact options for the mounting of the device means that MiCOM P11x can be applied using Flush, Panel, Wall, DIN Rail or Withdrawable techniques.
All devices include digital inputs and outputs and an inbuilt USB port for fast connection to setting software (MiCOM S1 or Easergy Studio).
