Motor-protective circuit-breakers have been manufactured by Eaton since 1932. Ideas and developments have decisively influenced the trends in the protection of motors since then. The results are progressive concepts and marketable product innovations that repeatedly assume the role of international trendsetting, pioneering products.
This long tradition in the motor protection field has helped establish and maintain a core competence, which has remained intact to this day. The term PKZ is not just the embodiment of quality, but also the synonym used by experts for motor-protective circuit-breakers.
