ECOMSA neutral earthing resistors are specially recommended for the protection of power transformers and generators against harmful currents in the event of earth faults in medium and low voltage (MV and LV) electrical distribution networks.

Our earthing resistors, conforming to EC289 and EEE32-1972 standards, are made of stainless steel resistor elements that offer a high thermal capacity to absorb high currents and include a current transformer. The element connections are bolted instead of welded, offering the possibility for an immediate assembly of spare parts on-site.
