The Mersen L080947 is a specialist electrical carbon brush intended to provide dependable current transfer between stationary and rotating components in compatible electric motors, generators and industrial electrical machinery. Manufactured by Mersen, this replacement component is suitable for professional maintenance, repair and overhaul operations where stable electrical contact is essential.
Carbon brushes are consumable electrical components that maintain contact with a rotating commutator or slip ring while allowing the equipment to operate continuously. The Mersen L080947 is designed to support consistent conductivity, controlled wear and reliable machine performance when installed in the correct brush holder and used with compatible equipment.
Selecting the correct replacement brush can help reduce electrical arcing, protect the commutator or slip-ring surface and minimise unplanned machinery downtime. Before ordering the Mersen L080947 carbon brush, verify the complete part number, dimensions, carbon grade, lead arrangement and equipment compatibility against the original component or the machine manufacturer’s technical documentation.

Reliable Electrical Contact for Rotating Equipment
Electrical carbon brushes create a conductive connection between fixed electrical wiring and a rotating commutator or slip ring. The brush gradually wears during normal operation and should be inspected regularly to maintain dependable equipment performance and prevent damage to associated electrical components.
Using the correct brush dimensions, material grade and terminal arrangement can help reduce uneven wear, excessive arcing and damage to the rotating contact surface. During replacement, the brush holder, spring pressure, flexible lead and commutator or slip ring should also be checked for contamination, scoring or mechanical damage.

Frequently Asked Questions
What is the Mersen L080947 used for?
The Mersen L080947 is an electrical carbon brush used to transfer current between stationary and rotating components in compatible motors, generators and industrial electrical equipment.
How can I confirm that the L080947 is compatible with my equipment?
Compare the complete part number, brush dimensions, carbon grade, lead arrangement and equipment model with the original component or the machine manufacturer’s documentation.
When should the carbon brush be replaced?
Replace the brush when it reaches the manufacturer’s minimum permitted length or shows signs of cracking, overheating, uneven wear, damaged leads or excessive sparking.
Should carbon brushes be replaced as a complete set?
Carbon brushes are commonly replaced as a matched set to support balanced spring pressure, consistent electrical contact and even wear across the machine.
What should be inspected during installation?
Inspect the brush holder, spring pressure, flexible connection and commutator or slip-ring surface. The replacement brush should move freely within the holder and make even contact with the rotating surface.
