In industries like OEM equipment manufacturing, high-load motors are omnipresent. Ensuring motors are safeguarded against overloads, short circuits, and other failures has become a critical priority for safe and efficient production.

Eaton, focusing on real-world OEM manufacturing scenarios, has expanded its motor protection product line with the PKZMX Motor Protection Circuit Breaker. This new series provides both short-circuit and overload protection, featuring wide current coverage, exceptional durability, and diverse accessories. It caters to the varied demands of mechanical equipment protection and industrial applications, paving the way for a safer, more efficient future.

1. Wide Current Range: Adapting to More Applications

The Eaton PKZMX offers a broad current range of 0.1–80A, with a rated voltage of up to 690V and a breaking capacity of up to 100kA. Certified with CCC, CE, and CB standards, it ensures reliable protection for motors across industries with varying power levels.

With a short-circuit trip threshold set at an average of 13 times In, the PKZMX effectively prevents damage caused by excessive loads or short circuits, ensuring motors can operate stably under high loads over extended periods.

2. Long Lifespan: Built to Endure

Designed for durability, the PKZMX achieves up to 100,000 mechanical and electrical operations, embedding safety and reliability into the production process.

The breaker complies with IEC60068 standards, offering robust resistance to vibration and shock. Its screw clamp terminal design enhances resilience in harsh environments, extending its service life. Users can also operate the breaker manually for switching at frequencies of up to 25 times per hour, making it ideal for maintenance and commissioning tasks.

3. Rich Accessories: Flexible and Customizable

Eaton provides a wide range of accessories for the PKZMX, allowing users to tailor the solution to their specific needs. Accessories include:

• Auxiliary and alarm contacts
