The Product


To minimize the financial impacts on your company with consumption energy, we present the Electromagnetic Retainer.

The device developed exclusively by Somatec Blocking has 13 models with different sizes and voltage ranges, varying according to the characteristics of the switchboard where it will be installed. Through an electronic system that identifies electrical transients in the electric current, the Electromagnetic Retainer eliminates disturbances arising from generation, transport and the way energy is consumed, reducing its energy consumption.

The Electromagnetic Retainer allows machines and equipment to work with an electrical energy supply without the imperfections existing in the network. Consequently, it is possible to verify through technical reports the reduction in energy consumption, the increase in motor performance, the increase in power factor and load factor, protection against burning equipment by lightning and much more, which finally generates more savings for your business.

Our results are technically verified by experienced and qualified electrical engineers in the fields of electrical measurements, by using top-rated gauged energy analyzers and the most reputable brands on the market.
The reduction in electric power consumption is always verified through comparative data extracted from energy analyzers and production worksheets, in periods with and without the use of the Electromagnetic Retainers.
*Examples QF - Production (same production for both periods)


Meeting the highest quality and safety technical standards, Somatec Blocking is the main reference for electric power reduction in the national market, with technically verified percentages. The Electromagnetic Retainers are used by many renowned companies in Brazil and abroad.
Somatec is also recognized by FIESP as the owner of the greatest technological innovation for electric power. In 2015, it received the Acelera Startup award, coveraged by TV network Rede Globo in the Jornal Nacional newscast.
