PKZ motor protection circuit breaker
Eaton's Moeller series PKZ fuseless motor-protective circuit breakers combine short-circuit and overload protection in a single device. Two versions are available, covering the entire voltage range from 0.1 A to 63 A. And this with only 18 different types, which saves storage space and simplifies project planning. The motor-protective circuit breakers are fully compatible with Eaton’s proven DIL contactor series, and they are therefore ideally suited for use in motor-starter combinations. All accessories, including the integrated auxiliary switches, trip indicators, voltage releases and door coupling rotary handles, can be used for both the PKZM0 and the PKZM4.
Core features
- Hand-operated motor-protective circuit breaker in accordance with IEC/EN 60947-4-1, VDE 0660 Part 102
- Rotary handle with ON & OFF switch-position indicator
- If used in conjunction with the appropriate accessories, the circuit breaker can be turned into a main switch or emergency-stop switch in accordance with EN 60204 and/or VDE 0113
- Isolating characteristics in accordance with IEC/EN 60947-3
- UL/CSA (including Types E and F) approvals for the North American market
- All setting ranges are short-circuit proof up to 50 kA (400 V)
- Special IP40, IP55 and IP65 housings offer high levels of protection against direct contact as well as ingress of water and particles; both surface- and flush-mounted enclosures are available.
- If used in conjunction with surface-mounting and flush-mounting enclosures, main switch and emergency-stop switch applications are also possible
Connections with just one clever “click” – the PKZ motor-protective circuit breaker with push-in technology
The push-in terminals enable safe and easy control-panel wiring with just one click – no tools required. This not only speeds up wiring by up to 50 %, but is also much safer thanks to the shock and vibration-resistant terminals. The PKZ motor starters with push-in terminals stand out for their higher rated current of up to 32 A and the screw-in/push-in combination option for use with three-phase busbar links.

Proven and trusted: PKZM0
The PKZM0 motor-protective circuit-breaker can switch motors from 0.16 A to 32 A, with a short-circuit rating of 150 kA up to 12 A, and of 50 kA up to 32 A.
Simple and versatile: PKZM4
The PKZM4 covers the current range from 16 A to 63 A and has a switching capacity of 50 kA. It not only allows for safe and simplified project planning, but also eliminates the need for a current limiter.
Ideal for push and impact actuation (pressing or hitting)
The PKZM01 motor-protective circuit breaker for motors up to 25 A is ideal for small machines and other applications where push or impact actuation is the preferred means of operation. In addition, special IP65 and IP40 housings with emergency-stop buttons are also available.
The PKZ as part of the xStart system
Many applications require an auxiliary contact with different contact configurations for interlocking and signaling. By using a motor starter, however, it becomes possible to implement a more direct, safe and efficient control design.
All the information at your fingertips thanks to SmartWire-DT
The PKZ motor starter combinations can be integrated into any automation environment via SmartWire-DT. By enhancing data transparency, SmartWire-DT increases the efficiency and reliability of the drives in the vicinity of the motor-protective circuit breaker.
Energy efficiency is currently a hot topic
With Eaton, your systems are automatically compliant with the ErP directive in a simple, fast and economical way, while significantly reducing your energy costs.
Expertise that we are happy to share - the Eaton Moeller series
Eaton has been manufacturing the PKZ motor-protective circuit breaker since 1932. Since then, our ideas and innovations have made a major contribution to advances in motor protection. In this regard, the name PKZ not only stands for quality, but has also become a synonym for motor-protective circuit breakers among experts.
