Safety interfaces for smart energy


EFEN focuses on the development, production and sales of safety equipment for low-voltage installations. The company has been producing current transformers since 2003. In 2006, EFEN expanded its product portfolio and added measuring equipment. “Against the background of the prevailing discussion about smart energy and the efficient use of our resources, communications are becoming more important,” says Managing Director Johannes Thomé. “Today, you have to be in control of the periphery of the smart grid, too.”

Acting in a dynamic market environment which is subject to macroeconomic developments and international politics, too, EFEN has always been strong in innovation. At present, the E3 ct-connection block is one of the company’s latest highlights. The smart switch rail is able to protect, measure and communicate, and can be used at different stages of expansion. Thanks to its modular basis, it is available ex works and can also be retrofitted into existing equipment. In addition to this, EFEN supplies transformer stations, cable stations, control cabinets, and other industrial and commercial equipment. Silas is another recent development: a fuse circuit breaker which is being developed continuously.

EFEN is a much sought-after partner among energy supply companies, the utilities, and infrastructure and industrial enterprises. Plumbers and manufacturers of switchboards are supplied via wholesalers and the parents company’s brand Hager. “We also cooperate with planning offices, architects and telecommunications companies,” says Managing Director Michael Lehr. “We also participate in tenders for infrastructure facilities.”

In order to make its brand more popular and to stage its latest developments, EFEN participates regularly in leading international trade fairs such as the Hanover Fair and the Light & Building in Frankfurt. The company also exhibits at regional trade fairs held by the utilities. EFEN is active worldwide and achieves around 50% of its annual turnover outside of Germany. It operates a subsidiary in China. In Europe, the company runs production facilities in Hungary and Poland. Mr. Lehr sees much more future potential abroad.

“We see promising perspectives in Asia and South America,” he says. “Our goal for the coming years is to transform into a solution provider,” adds Mr. Thomé. “Therefore, we staged only comprehensive solutions at the last Hanover fair. We were the only company to show multi-component applications instead of products. Our clients benefit greatly from this one-source approach. They have only one contact person, and we are able to offer them modular applications with additional features. We will stay true to our development and innovation-oriented strategy and hope that we will be able to establish EFEN as a premium brand for comprehensive solutions. We draw on many years of experience in the industry and are backed by our parent company Hager group. These are excellent preconditions.”
