Eaton has launched its new xEnergy Elite low voltage motor control and power distribution centre for loads up to 7,500 A and 690 VAC in an effort to provide greater uptime and flexibility, with maintenance cost savings, for business-critical applications in industries such as mining.

The xEnergy Elite motor control centre (MCC) complies with the relevant International Electrotechnical Commission (IEC) standards and is designed for maximum power availability and protection of operating as well as maintenance staff. It incorporates advanced motor control and protection technologies that optimise performance while protecting personnel and equipment; for instance by minimising the dangers associated with an arc flash event beyond the requirements of IEC TR 61641, Eaton says.

The MCC’s fully segregated dropper busbars, optional fully isolated main busbars and Elite patented contact system for withdrawable motor starters and energy feeders are specially designed to prevent an arc flash from occurring.

The Elite contact system allows for operation while the compartment door is closed, increasing personnel safety. With the use of a key, the units can be placed in the disconnect, test or connected position. The incoming air circuit breaker (ACB) is equipped with Eaton’s Arc Flash Reduction Maintenance System™, which significantly reduces incident energy during maintenance. It is only active when required, thereby preserving the protection against overcurrent under normal operating conditions.

The design of the xEnergy Elite MCC improves uptime and reduces the need for maintenance, according to Eaton. Thanks to the unique rotating contact technology of the Elite drawer units, contact wear on the vertical busbar is reduced to an absolute minimum. This ensures that the electrical connections are ideally positioned even in the event of a short-circuit or a heavy starting load to avoid sparking.

Since July 1, 2023, the use of Super Premium Efficiency motors (IE4) has become mandatory for motors with a rated output between 75 kW and 200 kW. The xEnergy Elite withdrawable motor starter units support the new utilisation categories for Premium Efficiency (IE3) and Super Premium Efficiency (IE4) motor switching and can be exchanged from the front without shutting down the system, enabling it to be serviced and expanded without interrupting production. This plug-and-play solution is tested for more than 1,000 mechanical operations, significantly higher than the IEC standard of 200.

The MCC’s small footprint offers increased flexibility based on high-density micro-drawer configurations. The busbars are virtually maintenance-free, Eaton claims, and all functions can be accessed from the front of the switchgear, so that the need for rear access is greatly reduced (both with the main busbar located at the back and on top). As a result, xEnergy Elite can be placed against the wall (requiring only 5 0 mm of clearance for ventilation purposes), which can save up to 2 sq.m per section, freeing up valuable floor space. Additionally, the system offers a shared main busbars solution, which further minimises the footprint and reduces the amount of copper used.

Furthermore, the specific requirements of customers needing rear cable compartments can be met with the latest development introduced to the system, featuring busbars located on top.

“Given that motor failure may cause production downtime, costly repairs and serious safety issues for personnel, the powerful control and protection provided by xEnergy Elite is a core element of a dependable and safe system,” Lukasz Przybecki, Product Manager for Low Voltage IEC Assemblies at Eaton, says.

Danfoss has entered into an agreement to acquire Eaton’s Hydraulics business, creating a “global leader in mobile and industrial hydraulics”, Kim Fausing, Danfoss’ President and CEO, says.

The company has agreed to pay $3.3 billion for the business, explaining that the acquisition is fully in line with Danfoss’ strategy to strengthen its core businesses and enhance customer value.

Fausing said the deal was a “once-in-a-lifetime opportunity” to combine the two companies’ largely complementary portfolios and geographic footprints.

“Eaton Hydraulics is a highly respected player in the global industry, recognised for its dedicated people and strong brands. By combining the knowledge and experience of the two businesses, our customers will benefit from unmatched expertise from a single partner,” he said.

“With this agreement, we continue to invest in our core hydraulics business and digital solutions to stay a strong technology partner.”

Craig Arnold, Eaton Chairman and CEO, said Eaton’s Hydraulics business will benefit greatly from being “part of a company that has hydraulics at its core”.

He added: “When complete, this deal will bring together two talented teams with deep hydraulics knowledge and expertise. And Eaton’s hydraulics team will be part of a company that is committed to becoming a global leader in mobile and industrial hydraulics. The combined business will also benefit customers and distributors by offering industry-leading technology and a much broader portfolio of hydraulic solutions.”

Danfoss says the two businesses are leaders in the industry and have many organisational similarities, including company culture and a focus on customers, R&D and quality. The combined business creates a broader presence across the world, while enabling Danfoss to enter the industrial hydraulics market served by Eaton Hydraulics, the company explained.

Eaton Hydraulics provides products for customers in markets such as agriculture, construction and industrial markets. It also supplies mining companies with harsh duty cycle component solutions and services.

The business will be transferred into the existing Danfoss business segment, Danfoss Power Solutions, adding around 11,000 employees and 2019 sales of $2.2 billion to the business segment, which will double the hydraulics business. Danfoss, today, has some 28,000 employees and 2019 sales of $7 billion. Accordingly, with this transaction, Danfoss will increase its size by one-third.

Eric Alström, President of Danfoss Power Solutions, said: “Hydraulics is our core, and we have for years strengthened our Power Solutions business through high customer focus, as well as through significant investments in technology leadership.

“I believe our customers will benefit from combining these two businesses into a full-line hydraulics player dedicated to innovation and with a broad offering of products, robust distribution channels and tremendous geographic reach.”

The transaction is subject to customary closing conditions and regulatory approvals and is expected to close by the end of the year.
