Maximum and minimum voltage coil, to be associated with OMU System brand circuit breakers. This coil triggers the circuit breaker to which it is associated when the voltage in it falls below a certain value, or exceeds a certain value.

The coil is always located on the circuit breaker on its left side.

A trip coil is a voltmetric relay that operates when the voltage is not within range and causes the tripping of the automatic or thermal-magnetic switch to which it is associated.

Note: If the voltage disappears completely, the trip will not occur.

Technical characteristics:

  • Manufacturer/Supplier: OMU System
  • Reference: OMBAUNTF
  • Operating voltage (Ue). 230Vac
  • Maximum voltage from which the trip occurs (Uvo): 280±5V
  • Minimum voltage below which tripping occurs (Uue): 170±5V
  • Width: 1 module, 18mm

Note: This over or under voltage trip coil is only valid for OMY Systems brand magnetothermic switches of both 6kA and 10kA.



Professional use material, install in compliance with the regulations in force at the place of installation.
