(Reuters) - Swiss engineering company ABB (ABBN.VX) was near an agreement Sunday to acquire U.S. manufacturer Thomas & Betts Corp (TNB.N) for about $ 4 billion, the Wall Street Journal reported, citing people familiar with the matter.

An agreement could be announced as soon as Monday, although the talks could still fall apart, the paper said on its Web site, citing the same unnamed sources.

ABB, which makes products used by oil, mining and utility companies, was not immediately available to comment.

Memphis-based Thomas & Betts makes electrical components for industrial companies in the United States, Canada and Europe. It had sales of about $2 billion in 2010 and is scheduled to report its 2011 and fourth-quarter results on Monday, the paper said.

The Zurich-headquartered company has been on a buying spree for the past two years and analysts have kept a close eye on the size of its war chest to see where it might pounce next.

Under the leadership of Chief Executive Joe Hogan, it returned to the M&A market after a lengthy absence, buying industrial motor business Baldor Electric for $4.2 billion in 2010, among other deals.

ABB had net cash of some $1 billion at the end of the third quarter. Acquisitions could potentially add another 3 to 4 percent to its overall growth rate, although in November, Hogan ruled out emptying its war chest for one single target.

Hogan has said ABB still had gaps in the United States and in the market for Programmable Logic Controllers (PLC) -- small equipment control devices.

In 2011 ABB, which competes with France's Schneider (SCHN.PA) and Germany's Siemens (SIEGn.DE), bought Australian software company Mincom, having in 2010 spent more than $1 billion on U.S. software company Ventyx.
