Eaton PKE Electronic Motor Protection Circuit Breaker 32A 690V Modular Design 121730 PKE-XTUA-32

Eaton 121730 PKE-XTUA-32 electronic motor protection circuit breaker provides advanced protection and control for electric motors operating at 32A current rating and 690V voltage. Designed within the PKE series, this device offers long-term reliability with precise tripping characteristics and wide adjustment ranges, ideally suited for industrial, manufacturing, and automation applications.

This motor protection circuit breaker is manually actuated with a rotating handle that clearly indicates ON, OFF, and TRIPPED states, enhancing user operation safety and maintenance efficiency. Its robust short-circuit proof rating up to 100 kA (at 400 V) eliminates the need for pre-fusing or complex short-circuit current calculations, reducing installation effort and cost.

The PKE series complements Eaton’s PKZ device family by integrating advanced electronic overload protection, providing superior alternative to traditional bimetal solutions for motor currents up to 65 A. It safeguards motors from faults including overload, high voltage, and electrical short circuits.

The breaker features a modular design enabling the use of standard components and accessories such as auxiliary contacts, trip indicating auxiliary contacts, voltage releases, and shunt trips, which can be installed without tools to minimize installation times. It is compatible with the SmartWire-DT communication system, allowing direct transfer of measurement and status data to control units and HMIs for enhanced process visualization and system availability.
