Whether it’s fuses or circuit breakers, Eaton has exactly what you need to protect installations, operators and end clients. Plus, Eaton’s SmartWire DT connection technology makes it possible to quickly and easily determine breaker status. The PKE circuit breaker supplies information on load currents, breaker values and early warning alerts. This provides for early detection of anomalies and critical issues.
In critical applications like rail, marine or mobile equipment and for applications using long cables the protection of circuits can become a challenge. Hydraulic-magnetic circuit breakers customizable for various situations are the perfect solution for many of those applications. And the Eaton breakers do not only offer reliable operation but also very compact sizes and mounting options.
Protecting and managing 24V DC control circuits remotely is easier today than ever before. Electronic protection devices, like the PXS24 detect overloads quickly and disconnect before further damage occurs. The modular devices allow channel specific control, switching and signaling while all the functions can also be accessed and controlled remotely. The PXS24 modules are perfectly harmonized with the Eaton power supplies.
Operating data can be read out by the integrated Modbus RTU and used to enable other technology. A wide range of field bus and industrial Ethernet communication links are available for digital circuit breakers and frequency inverters.
SmartWire-DT demonstrates its strength as a quickly-integratable connectivity system, in particular where contact notifications and warning signals are important, or in the collection of current values from the PKE, for example.
Reliability, enhanced safety features and precise data measurement distinguish digital circuit breakers made by Eaton. Compliant with ISO50001, the same measurement and communication technology is used in circuit breakers up to 6300A, everything from simple connections right through to complete sub-distribution.
Multiple installation options are available, including rear and side-panel actuation, facilitating flexibility and space-saving. Full compatibility of accessories simplifies switching over to digital circuit breakers. Integrated energy measurement with category 1 accuracy as per IEC 61557-12 is also available.
Variation in motor current over time is a key indicator for planning preventive maintenance. With the new digital NZM circuit breaker a service life indicator is able to provide optimum life-cycle management. Breakers provide current values as well as a digital motor image, diagnosis data and much more. Data on all electrical systems is collected and communicated without the need for additional sensors.
Leakage current and harmonics constitute major challenges in systems utlilising inverters. Digital, all-current sensitive FI circuit breakers from Eaton prevent unwanted tripping and reliably disconnect when maximum thresholds are exceeded. In addition, warning signals can be read off the device itself or transmitted digitally. Eaton also provides a wide range of safety fuses for protecting inverters. This solution is especially well suited for applications in the North American market, where it can provide for a high short-circuit threshold in the electrical cabinet.
