Circuit breaker for transformer protection PKZM0-T Push-In 1..1.6A PKZM0-1.6-T-PI 199168

### Circuit breaker for transformer protection – reliable protection and quick installation

This three-pole PKZM0-T circuit breaker from Eaton is a reliable solution for protecting transformers in electrical installations. Designed to operate at voltages up to 690V AC, it provides effective protection against overload and short circuit, guaranteeing the safety and continuity of the installation. This circuit breaker combines thermal and electromagnetic protection functions, offering comprehensive protection without the need for additional fuses.

Design and application

The PKZM0-T circuit breaker is designed for mounting on a DIN rail (optional) or otherwise, providing installation flexibility. Its compact design saves space in the switchgear cabinet. Push-in spring terminals significantly speed up the wiring process – by up to 50% compared to traditional screw terminals. This solution minimizes downtime during installation and maintenance. Additionally, Push-in technology provides high resistance to vibration and shock, which translates to durability and reliability of connections.

Key features and benefits

• Quick installation: Push-in spring terminals allow for quick connection of wires without tools.
• High vibration resistance: Push-in technology guarantees stable connections even in harsh working conditions.
• Comprehensive protection: Integrated thermal and electromagnetic protection protects against overload and short circuit.
• Wide adjustment range: The setting range of the overload release from 1 to 1.6 A allows for precise adaptation to the load characteristics.
• High short-circuit breaking capacity: The rated short-circuit breaking capacity Icu is as high as 150 kA at 400 V, ensuring safety in the event of a short circuit.
• Versatility: Designed to protect single-phase and three-phase transformers with voltages up to 690 V AC.
• Durable construction: Made of high-quality materials, ensuring a long service life of the device.

Technical parameters in practice

The PKZM0-T circuit breaker is characterized by a continuous rated current of 1.6 A and an overload release setting range of 1 to 1.6 A. The short-circuit breaking capacity of 150 kA at 400 V guarantees an effective response in the event of a failure. Protection class IP20 provides protection against touch and contamination. Power losses of 4.92 W minimize the impact on the energy efficiency of the installation. This makes the device meet the requirements of modern electrical installations, ensuring both safety and efficiency.
