The operating element for the 6R MATRIX supervision relay functional elements are designated 6RX & are based on our 6R Series relays.
The operating element of the 6RX12 comprises a single 6R heavy-duty attracted armature control relay with a single operating coil & delay slug. The relay is normally operated to indicate a healthy trip circuit supply while a slug is fitted to provide a delay on drop out & avoid nuisance tripping due to transients.
Under healthy conditions, the coil is energized & if the supply fails, the relay will drop out after a short time delay to initiate a supply fail alarm.
Contacts are constructed from silver / copper alloy, shaped & positioned to ensure very reliable, low resistance operation. Over travel of the contacts during each operation causes a wiping action ensuring a clean “make”.
