The move will allow the Cork, Ireland-based company to focus on its bigger building technologies and solutions business, which makes building heating and ventilation, and air conditioning systems.

The power solutions business accounted for 24 percent of the company's total revenue of $30.17 billion in 2017. The unit had $1.6 billion in earnings before interest, taxes, depreciation and amortization.

The building technologies and solutions business had $22.80 billion in sales in 2017.

The company said it expects to complete its assessment of strategic alternatives for the power solutions business over the next several months. (Reporting by Ankit Ajmera in Bengaluru; Editing by Maju Samuel)
