Terra Power Systems, a Bellingham-based manufacturer of electricity distribution devices, has been acquired by Littelfuse Inc., a multinational electronics firm based in Chicago, Ill.

Terra Power’s products are designed for buses and semi trucks, as well as a variety of heavy duty vehicles used in construction, agricultural or military applications.

Littelfuse, a public company that trades on the Nasdaq stock market, operates more than 20 sales, distribution, manufacturing and engineering facilities around the world.

It sells circuit-protection products used in virtually every market that requires electrical energy, including the automotive, consumer electronics and industrial equipment sectors.

Eric Graham, president and co-founder of Terra Power, said the Bellingham company does not expect any changes to its local operations or its staff. But it will now have the benefit of Littelfuse’s broad sales infrastructure and international footprint.

Shared values and visions between the two firms also made the merger a good fit, he said.

“There was a lot of synergies, as well as a lot of similarities,” Graham said.

Terra Power Systems employs about 25 people in the Bellingham area.

The company was founded in 2009.
