Over- or low-voltage firing coil for MCB circuit breaker - OMU

Coil of maximum and minimum voltage, to associate with magnetothermic brand OMU Systems. This coil causes the firing of the mcb circuit breaker to which it is associated when the voltage of the same descends from a certain value, or exceeds a certain value.

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

A trigger coil is a voltimetric relay that acts when the voltage is not in range and causes the automatic switch or mcb circuit breaker to which it is associated to fire.

Note: If the tension disappears completely, the shot will not occur.

Specifications:

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

Note: This over or low voltage firing coil is only valid for OMY Systems brand magntetothermics of both 6kA and 10kA.
