Eaton redesigns M-Force three-phase loadbreak switch for 2015

October 29, 2015 – Eaton announced it redesigned its 3-phase distribution class switches to improve reliability in utility, mining, oil and gas, renewable and other industrial and commercial applications. Eaton’s Cooper Power series M-Force three-phase switch includes design features for operation in power distribution feeds. The gang-operated, overhead loadbreak switch provides sectionalizing, paralleling, bypassing or isolating in 15 kV, 25 kV, and 35 kV voltage classifications.

Eaton says it is the only manufacturer with distribution-class loadbreak switches that include reverse loop contacts, typically incorporated in transmission switches, to improve power reliability. The Cooper Power series M-Force switch is designed to maintain cooler running temperatures, so that it can last longer, the company explains.

Now, the M-Force switch incorporates a stainless steel bell-crank for better corrosion resistance and a redesigned snuffer tube, Eaton says. The new Reliabreak holder has fewer components and “simpler, more consistent alignment”, it adds.
