Series Eaton - PKNM

Eaton PKNM Series

The Eaton PKNM series is a complete line of modular residual current circuit breakers (RCBOs) designed for modern electrical installations. These 1+N pole devices combine overcurrent protection and earth leakage detection in a single compact unit. Built for reliability and ease of use, the PKNM series helps electricians and installers deliver safe, code-compliant panels without taking up extra space.

Easy Installation and Space Saving

One of the biggest advantages of the PKNM series is how quickly it fits into standard distribution boards. Each unit snaps directly onto a DIN rail and replaces the need for a separate miniature circuit breaker and residual current device. This saves valuable panel space, cuts down on wiring time, and reduces the chance of connection errors. The clear labeling and straightforward terminal design make commissioning and troubleshooting fast and hassle-free.

Reliable Protection for Every Load Type

The PKNM series offers both B and C tripping curves to match different electrical loads. Use the B curve for standard resistive loads like lighting and heating, and switch to the C curve when protecting motors, transformers, or equipment with higher inrush currents. All models feature a 30mA sensitivity rating, providing strong protection against electric shock and earth faults. Optional auxiliary contacts (marked with “A” in the product code) allow for remote monitoring and alarm signaling, giving you more control over your installation.

Flexible Ratings for Residential and Commercial Use

With current ratings ranging from 6A to 32A, the PKNM series covers almost every common circuit requirement. Whether you are wiring a new home, upgrading an office panel, or working on a light commercial project, you will find the right breaker for the job. The modular design ensures compatibility with standard Eaton accessories and busbar systems, making it easy to scale your projects without switching brands.

Built to Last, Backed by Eaton Quality

Eaton has earned a strong reputation for durable, high-performance electrical components, and the PKNM series continues that tradition. These breakers are engineered to withstand daily use, resist wear, and maintain consistent performance over time. Clear visual indicators show tripped status at a glance, simplifying maintenance and reducing downtime. Choose the Eaton PKNM series for a smart, safe, and installer-friendly solution that delivers peace of mind on every job.
