The circuit breakers allow users to choose Class 5, 10, 15 or 20 trip characteristics (the number of seconds before tripping) using a rotary selector. A second calibrated rotary dial is provided for setting the trip current. The inherent stability of the electronic trip system ensures that the settings are accurately maintained throughout the life of the unit, even in adverse operating conditions.
The units are fully compatible with accessories from Eaton’s Moeller xStart range. This means that, when they are used in conjunction with Eaton’s Moeller DIL contactors, motor starters can quickly be assembled using tool-less plug-in connectors that save time and money by eliminating the need for conventional wiring between the contactor and the protective device.PKE circuit breakers also support Eaton’s Moeller SmartWire-Darwin in-panel fieldbus system that replaces conventional control wiring with plug-in connections. When used with SmartWire-Darwin, the new devices can provide information about key aspects of their operation—including maximum motor current, trip status, fault warnings and setting details—to the connected control system. This information is an invaluable aid to fault-finding and commissioning.
The new PKE electronic motor protection circuit breaker range includes the PKE12, suitable for motor currents from 0.3 A to 12 A, the PKE32, for motor currents from 3 A to 32 A, and in the future the PKE65 for motor currents from 8 A to 65 A.
All types have an operating temperature range of -25ºC to +55ºC, and all are fully compliant with relevant EU and international standards, including IEC/EN 60947-4-1, VDE 0660, UL 508 and CSA C 22.2 No. 14.
