Motor-protective circuit-breaker with electronic wide-range overload protection

Eaton has extended its range of PKE motor-protective circuit-breaker with wide-range overload protection. The new PKE 65 has a compact, modular design providing optimum flexibility for motor currents up to 65A. Modular standard components for creating motor starters are also perfectly matched and easy to combine. Users can also make use of accessories from the Eaton PKZ system, providing easy to exchange and perfectly matched devices.

Thanks to their special features, the PKE motor-protective circuit-breakers offer an interesting alternative to bimetal devices, along with several key benefits. These include large setting ranges, a low heat dissipation, tripping classes also higher then Class 10, as well as precise and extremely long-term stable tripping characteristics. The large current setting ranges also reduce the number of variants needed by up to 80 percent compared with bimetal type devices.

The PKE-SWD modular COM interface for PKE12, PKE32 and PKE65 motor-protective circuit-breakers, and the PKE-SWD-32 interface for MSC-DEA motor starter combinations with PKE12 and PKE32 motor-protective circuit-breakers enable the actual current of the drive and the thermal motor load to be measured as well as status or overload. The data is transferred via SmartWire-DT directly to the controller and is made available throughout the entire plant for condition monitoring or for remote maintenance tasks.
